Analog and Digital Signals in Electrical Engineering
In electrical engineering, the signal—a fundamental quantity—represents
information, whether it be digital or analog. When expressed mathematically, a
signal is just a function. Digital signals have discrete values, whereas analog
signals have continuous values. 3 The signal's independent variable may be
space (pictures), time (speech, for instance), or integers (denoting the
sequencing of letters and numbers in the football score).
a. Signals in Analog
Your vocal cords excite acoustic resonances in your vocal tract to
produce analog signals, which are typically specified over continuous
independent Analog and Digital Signals in Electrical Engineering
variable(s). The speech signal thus corresponds to a function with
independent variables of space and time and a value corresponding to air
pressure, as the consequence is pressure waves traveling in the air: S (x, t)
In this case, spatial coordinates are indicated by the vector notation x.
You are analyzing the voice signal at a specific spatial point, let's say x0,
while you record someone speaking.
Photographs are continuous-valued signals that are defined over space
and are static. The optical reflection qualities of black and white images
are limited to a single value at each point in space.
Reflectivity's dependence on the optical spectrum is expressed by the
values in color photographs. Painters discovered long ago that combining
the so-called fundamental colors—yellow, blue, and red—could create
incredibly lifelike color images. Therefore, a separate set of colors is
utilized in images, which are typically thought of as having three values
at every point in space: How much blue, green, and red are there? Color
images are multivalued vector-valued signals in mathematics: s (x)=(r
(x),g (x),b (x)) T.
b. There are several intriguing examples where the analog signal is
dependent on a discrete variable rather than a continuous one, like time.
For instance, hourly temperature data exhibit continuous analog values,
but the integers are (basically) the signal's independent variable.
Signals in Digital Form
The term "digital" denotes a discrete-valued signal with an independent
variable of integer value. Digital data contains both symbols and numbers
(characters typed on the keyboard, for example). For information
manipulation and transformation, computers rely on digital
representations. Each symbol is represented by a distinct integer and has
no numerical value. A seven-bit integer is used to represent the capital
and lowercase letters, digits, punctuation, and other symbols in the ASCII
character code. For instance, the letter A is represented by the number 65
in the ASCII code, and the letter a by the number 97.

the so-called fundamental colors—yellow, blue, and red—could create
incredibly lifelike color images. Therefore, a separate set of colors is
utilized in images, which are typically thought of as having three values
at every point in space: How much blue, green, and red are there? Color
images are multivalued vector-valued signals in mathematics: s (x)=(r
(x),g (x),b (x)) T.
b. There are several intriguing examples where the analog signal is
dependent on a discrete variable rather than a continuous one, like time.
For instance, hourly temperature data exhibit continuous analog values,
but the integers are (basically) the signal's independent variable.
Signals in Digital Form
The term "digital" denotes a discrete-valued signal with an independent
variable of integer value. Digital data contains both symbols and numbers
(characters typed on the keyboard, for example). For information
manipulation and transformation, computers rely on digital
representations. Each symbol is represented by a distinct integer and has
no numerical value. A seven-bit integer is used to represent the capital
and lowercase letters, digits, punctuation, and other symbols in the ASCII
character code. For instance, the letter A is represented by the number 65
in the ASCII code, and the letter a by the number 97.
In electrical engineering, the signal—a fundamental quantity—represents
information, whether it be digital or analog. When expressed mathematically, a
signal is just a function. Digital signals have discrete values, whereas analog
signals have continuous values. 3 The signal's independent variable may be
space (pictures), time (speech, for instance), or integers (denoting the
sequencing of letters and numbers in the football score).
a. Signals in Analog
Your vocal cords excite acoustic resonances in your vocal tract to
produce analog signals, which are typically specified over continuous
independent Analog and Digital Signals in Electrical Engineering
variable(s). The speech signal thus corresponds to a function with
independent variables of space and time and a value corresponding to air
pressure, as the consequence is pressure waves traveling in the air: S (x, t)
In this case, spatial coordinates are indicated by the vector notation x.
You are analyzing the voice signal at a specific spatial point, let's say x0,
while you record someone speaking.
Photographs are continuous-valued signals that are defined over space
and are static. The optical reflection qualities of black and white images
are limited to a single value at each point in space.

character code. For instance, the letter A is represented by the number 65
in the ASCII code, and the letter a by the number 97.
In electrical engineering, the signal—a fundamental quantity—represents
information, whether it be digital or analog. When expressed mathematically, a
signal is just a function. Digital signals have discrete values, whereas analog
signals have continuous values. 3 The signal's independent variable may be
space (pictures), time (speech, for instance), or integers (denoting the
sequencing of letters and numbers in the football score).
a. Signals in Analog
Your vocal cords excite acoustic resonances in your vocal tract to
produce analog signals, which are typically specified over continuous
independent Analog and Digital Signals in Electrical Engineering
variable(s). The speech signal thus corresponds to a function with
independent variables of space and time and a value corresponding to air
pressure, as the consequence is pressure waves traveling in the air: S (x, t)
In this case, spatial coordinates are indicated by the vector notation x.
You are analyzing the voice signal at a specific spatial point, let's say x0,
while you record someone speaking.
Photographs are continuous-valued signals that are defined over space
and are static. The optical reflection qualities of black and white images
are limited to a single value at each point in space.
Reflectivity's dependence on the optical spectrum is expressed by the
values in color photographs. Painters discovered long ago that combining
the so-called fundamental colors—yellow, blue, and red—could create
incredibly lifelike color images. Therefore, a separate set of colors is
utilized in images, which are typically thought of as having three values
at every point in space: How much blue, green, and red are there? Color
images are multivalued vector-valued signals in mathematics: s (x)=(r
(x),g (x),b (x)) T.
b. There are several intriguing examples where the analog signal is
dependent on a discrete variable rather than a continuous one, like time.
For instance, hourly temperature data exhibit continuous analog values,
but the integers are (basically) the signal's independent variable.
Signals in Digital Form
The term "digital" denotes a discrete-valued signal with an independent
variable of integer value. Digital data contains both symbols and numbers
(characters typed on the keyboard, for example). For information
manipulation and transformation, computers rely on digital
representations. Each symbol is represented by a distinct integer and has
no numerical value. A seven-bit integer is used to represent the capital
and lowercase letters, digits, punctuation, and other symbols in the ASCII
character code. For instance, the letter A is represented by the number 65

Photographs are continuous-valued signals that are defined over space
and are static. The optical reflection qualities of black and white images
are limited to a single value at each point in space.
Reflectivity's dependence on the optical spectrum is expressed by the
values in color photographs. Painters discovered long ago that combining
the so-called fundamental colors—yellow, blue, and red—could create
incredibly lifelike color images. Therefore, a separate set of colors is
utilized in images, which are typically thought of as having three values
at every point in space: How much blue, green, and red are there? Color
images are multivalued vector-valued signals in mathematics: s (x)=(r
(x),g (x),b (x)) T.
b. There are several intriguing examples where the analog signal is
dependent on a discrete variable rather than a continuous one, like time.
For instance, hourly temperature data exhibit continuous analog values,
but the integers are (basically) the signal's independent variable.
Signals in Digital Form
The term "digital" denotes a discrete-valued signal with an independent
variable of integer value. Digital data contains both symbols and numbers
(characters typed on the keyboard, for example). For information
manipulation and transformation, computers rely on digital
representations. Each symbol is represented by a distinct integer and has
no numerical value. A seven-bit integer is used to represent the capital
and lowercase letters, digits, punctuation, and other symbols in the ASCII
character code. For instance, the letter A is represented by the number 65
in the ASCII code, and the letter a by the number 97.
In electrical engineering, the signal—a fundamental quantity—represents
information, whether it be digital or analog. When expressed mathematically, a
signal is just a function. Digital signals have discrete values, whereas analog
signals have continuous values. 3 The signal's independent variable may be
space (pictures), time (speech, for instance), or integers (denoting the
sequencing of letters and numbers in the football score).
a. Signals in Analog
Your vocal cords excite acoustic resonances in your vocal tract to
produce analog signals, which are typically specified over continuous
independent Analog and Digital Signals in Electrical Engineering
variable(s). The speech signal thus corresponds to a function with
independent variables of space and time and a value corresponding to air
pressure, as the consequence is pressure waves traveling in the air: S (x, t)
In this case, spatial coordinates are indicated by the vector notation x.

manipulation and transformation, computers rely on digital
representations. Each symbol is represented by a distinct integer and has
no numerical value. A seven-bit integer is used to represent the capital
and lowercase letters, digits, punctuation, and other symbols in the ASCII
character code. For instance, the letter A is represented by the number 65
in the ASCII code, and the letter a by the number 97.
In electrical engineering, the signal—a fundamental quantity—represents
information, whether it be digital or analog. When expressed mathematically, a
signal is just a function. Digital signals have discrete values, whereas analog
signals have continuous values. 3 The signal's independent variable may be
space (pictures), time (speech, for instance), or integers (denoting the
sequencing of letters and numbers in the football score).
a. Signals in Analog
Your vocal cords excite acoustic resonances in your vocal tract to
produce analog signals, which are typically specified over continuous
independent Analog and Digital Signals in Electrical Engineering
variable(s). The speech signal thus corresponds to a function with
independent variables of space and time and a value corresponding to air
pressure, as the consequence is pressure waves traveling in the air: S (x, t)
In this case, spatial coordinates are indicated by the vector notation x.
You are analyzing the voice signal at a specific spatial point, let's say x0,
while you record someone speaking.
Photographs are continuous-valued signals that are defined over space
and are static. The optical reflection qualities of black and white images
are limited to a single value at each point in space.
Reflectivity's dependence on the optical spectrum is expressed by the
values in color photographs. Painters discovered long ago that combining
the so-called fundamental colors—yellow, blue, and red—could create
incredibly lifelike color images. Therefore, a separate set of colors is
utilized in images, which are typically thought of as having three values
at every point in space: How much blue, green, and red are there? Color
images are multivalued vector-valued signals in mathematics: s (x)=(r
(x),g (x),b (x)) T.
b. There are several intriguing examples where the analog signal is
dependent on a discrete variable rather than a continuous one, like time.
For instance, hourly temperature data exhibit continuous analog values,
but the integers are (basically) the signal's independent variable.

You are analyzing the voice signal at a specific spatial point, let's say x0,
while you record someone speaking.
Photographs are continuous-valued signals that are defined over space
and are static. The optical reflection qualities of black and white images
are limited to a single value at each point in space.
Reflectivity's dependence on the optical spectrum is expressed by the
values in color photographs. Painters discovered long ago that combining
the so-called fundamental colors—yellow, blue, and red—could create
incredibly lifelike color images. Therefore, a separate set of colors is
utilized in images, which are typically thought of as having three values
at every point in space: How much blue, green, and red are there? Color
images are multivalued vector-valued signals in mathematics: s (x)=(r
(x),g (x),b (x)) T.
b. There are several intriguing examples where the analog signal is
dependent on a discrete variable rather than a continuous one, like time.
For instance, hourly temperature data exhibit continuous analog values,
but the integers are (basically) the signal's independent variable.
Signals in Digital Form
The term "digital" denotes a discrete-valued signal with an independent
variable of integer value. Digital data contains both symbols and numbers
(characters typed on the keyboard, for example). For information
manipulation and transformation, computers rely on digital
representations. Each symbol is represented by a distinct integer and has
no numerical value. A seven-bit integer is used to represent the capital
and lowercase letters, digits, punctuation, and other symbols in the ASCII
character code. For instance, the letter A is represented by the number 65
in the ASCII code, and the letter a by the number 97.
In electrical engineering, the signal—a fundamental quantity—represents
information, whether it be digital or analog. When expressed mathematically, a
signal is just a function. Digital signals have discrete values, whereas analog
signals have continuous values. 3 The signal's independent variable may be
space (pictures), time (speech, for instance), or integers (denoting the
sequencing of letters and numbers in the football score).
a. Signals in Analog
Your vocal cords excite acoustic resonances in your vocal tract to
produce analog signals, which are typically specified over continuous
independent Analog and Digital Signals in Electrical Engineering
variable(s). The speech signal thus corresponds to a function with

pressure, as the consequence is pressure waves traveling in the air: S (x, t)

Signals in Digital Form
The term "digital" denotes a discrete-valued signal with an independent
variable of integer value. Digital data contains both symbols and numbers
(characters typed on the keyboard, for example). For information
manipulation and transformation, computers rely on digital
representations. Each symbol is represented by a distinct integer and has
no numerical value. A seven-bit integer is used to represent the capital
and lowercase letters, digits, punctuation, and other symbols in the ASCII
character code. For instance, the letter A is represented by the number 65
in the ASCII code, and the letter a by the number 97.
In electrical engineering, the signal—a fundamental quantity—represents
information, whether it be digital or analog. When expressed mathematically, a
signal is just a function. Digital signals have discrete values, whereas analog
signals have continuous values. 3 The signal's independent variable may be
space (pictures), time (speech, for instance), or integers (denoting the
sequencing of letters and numbers in the football score).
a. Signals in Analog
Your vocal cords excite acoustic resonances in your vocal tract to
produce analog signals, which are typically specified over continuous
independent Analog and Digital Signals in Electrical Engineering
variable(s). The speech signal thus corresponds to a function with
independent variables of space and time and a value corresponding to air
pressure, as the consequence is pressure waves traveling in the air: S (x, t)
In this case, spatial coordinates are indicated by the vector notation x.
You are analyzing the voice signal at a specific spatial point, let's say x0,
while you record someone speaking.
Photographs are continuous-valued signals that are defined over space
and are static. The optical reflection qualities of black and white images
are limited to a single value at each point in space.
Reflectivity's dependence on the optical spectrum is expressed by the
values in color photographs. Painters discovered long ago that combining
the so-called fundamental colors—yellow, blue, and red—could create
incredibly lifelike color images. Therefore, a separate set of colors is
utilized in images, which are typically thought of as having three values
at every point in space: How much blue, green, and red are there? Color
images are multivalued vector-valued signals in mathematics: s (x)=(r
(x),g (x),b (x)) T.
b. There are several intriguing examples where the analog signal is
dependent on a discrete variable rather than a continuous one, like time.

variable(s). The speech signal thus corresponds to a function with
independent variables of space and time and a value corresponding to air
pressure, as the consequence is pressure waves traveling in the air: S (x, t)
In this case, spatial coordinates are indicated by the vector notation x.
You are analyzing the voice signal at a specific spatial point, let's say x0,
while you record someone speaking.
Photographs are continuous-valued signals that are defined over space
and are static. The optical reflection qualities of black and white images
are limited to a single value at each point in space.
Reflectivity's dependence on the optical spectrum is expressed by the
values in color photographs. Painters discovered long ago that combining
the so-called fundamental colors—yellow, blue, and red—could create
incredibly lifelike color images. Therefore, a separate set of colors is
utilized in images, which are typically thought of as having three values
at every point in space: How much blue, green, and red are there? Color
images are multivalued vector-valued signals in mathematics: s (x)=(r
(x),g (x),b (x)) T.
b. There are several intriguing examples where the analog signal is
dependent on a discrete variable rather than a continuous one, like time.
For instance, hourly temperature data exhibit continuous analog values,
but the integers are (basically) the signal's independent variable.
Signals in Digital Form
The term "digital" denotes a discrete-valued signal with an independent
variable of integer value. Digital data contains both symbols and numbers
(characters typed on the keyboard, for example). For information
manipulation and transformation, computers rely on digital
representations. Each symbol is represented by a distinct integer and has
no numerical value. A seven-bit integer is used to represent the capital
and lowercase letters, digits, punctuation, and other symbols in the ASCII
character code. For instance, the letter A is represented by the number 65
in the ASCII code, and the letter a by the number 97.
In electrical engineering, the signal—a fundamental quantity—represents
information, whether it be digital or analog. When expressed mathematically, a
signal is just a function. Digital signals have discrete values, whereas analog
signals have continuous values. 3 The signal's independent variable may be
space (pictures), time (speech, for instance), or integers (denoting the
sequencing of letters and numbers in the football score).

dependent on a discrete variable rather than a continuous one, like time.
For instance, hourly temperature data exhibit continuous analog values,
but the integers are (basically) the signal's independent variable.
Signals in Digital Form
The term "digital" denotes a discrete-valued signal with an independent
variable of integer value. Digital data contains both symbols and numbers
(characters typed on the keyboard, for example). For information
manipulation and transformation, computers rely on digital
representations. Each symbol is represented by a distinct integer and has
no numerical value. A seven-bit integer is used to represent the capital
and lowercase letters, digits, punctuation, and other symbols in the ASCII
character code. For instance, the letter A is represented by the number 65
in the ASCII code, and the letter a by the number 97.
In electrical engineering, the signal—a fundamental quantity—represents
information, whether it be digital or analog. When expressed mathematically, a
signal is just a function. Digital signals have discrete values, whereas analog
signals have continuous values. 3 The signal's independent variable may be
space (pictures), time (speech, for instance), or integers (denoting the
sequencing of letters and numbers in the football score).
a. Signals in Analog
Your vocal cords excite acoustic resonances in your vocal tract to
produce analog signals, which are typically specified over continuous
independent Analog and Digital Signals in Electrical Engineering
variable(s). The speech signal thus corresponds to a function with
independent variables of space and time and a value corresponding to air
pressure, as the consequence is pressure waves traveling in the air: S (x, t)
In this case, spatial coordinates are indicated by the vector notation x.
You are analyzing the voice signal at a specific spatial point, let's say x0,
while you record someone speaking.
Photographs are continuous-valued signals that are defined over space
and are static. The optical reflection qualities of black and white images
are limited to a single value at each point in space.
Reflectivity's dependence on the optical spectrum is expressed by the
values in color photographs. Painters discovered long ago that combining
the so-called fundamental colors—yellow, blue, and red—could create
incredibly lifelike color images. Therefore, a separate set of colors is
utilized in images, which are typically thought of as having three values
at every point in space: How much blue, green, and red are there? Color
images are multivalued vector-valued signals in mathematics: s (x)=(r
(x),g (x),b (x)) T.

a. Signals in Analog
Your vocal cords excite acoustic resonances in your vocal tract to
produce analog signals, which are typically specified over continuous
independent Analog and Digital Signals in Electrical Engineering
variable(s). The speech signal thus corresponds to a function with
independent variables of space and time and a value corresponding to air
pressure, as the consequence is pressure waves traveling in the air: S (x, t)
In this case, spatial coordinates are indicated by the vector notation x.
You are analyzing the voice signal at a specific spatial point, let's say x0,
while you record someone speaking.
Photographs are continuous-valued signals that are defined over space
and are static. The optical reflection qualities of black and white images
are limited to a single value at each point in space.
Reflectivity's dependence on the optical spectrum is expressed by the
values in color photographs. Painters discovered long ago that combining
the so-called fundamental colors—yellow, blue, and red—could create
incredibly lifelike color images. Therefore, a separate set of colors is
utilized in images, which are typically thought of as having three values
at every point in space: How much blue, green, and red are there? Color
images are multivalued vector-valued signals in mathematics: s (x)=(r
(x),g (x),b (x)) T.
b. There are several intriguing examples where the analog signal is
dependent on a discrete variable rather than a continuous one, like time.
For instance, hourly temperature data exhibit continuous analog values,
but the integers are (basically) the signal's independent variable.
Signals in Digital Form
The term "digital" denotes a discrete-valued signal with an independent
variable of integer value. Digital data contains both symbols and numbers
(characters typed on the keyboard, for example). For information
manipulation and transformation, computers rely on digital
representations. Each symbol is represented by a distinct integer and has
no numerical value. A seven-bit integer is used to represent the capital
and lowercase letters, digits, punctuation, and other symbols in the ASCII
character code. For instance, the letter A is represented by the number 65
in the ASCII code, and the letter a by the number 97.
In electrical engineering, the signal—a fundamental quantity—represents
information, whether it be digital or analog. When expressed mathematically, a
signal is just a function. Digital signals have discrete values, whereas analog
signals have continuous values. 3 The signal's independent variable may be
space (pictures), time (speech, for instance), or integers (denoting the

images are multivalued vector-valued signals in mathematics: s (x)=(r
(x),g (x),b (x)) T.
b. There are several intriguing examples where the analog signal is
dependent on a discrete variable rather than a continuous one, like time.
For instance, hourly temperature data exhibit continuous analog values,
but the integers are (basically) the signal's independent variable.
Signals in Digital Form
The term "digital" denotes a discrete-valued signal with an independent
variable of integer value. Digital data contains both symbols and numbers
(characters typed on the keyboard, for example). For information
manipulation and transformation, computers rely on digital
representations. Each symbol is represented by a distinct integer and has
no numerical value. A seven-bit integer is used to represent the capital
and lowercase letters, digits, punctuation, and other symbols in the ASCII
character code. For instance, the letter A is represented by the number 65
in the ASCII code, and the letter a by the number 97.
In electrical engineering, the signal—a fundamental quantity—represents
information, whether it be digital or analog. When expressed mathematically, a
signal is just a function. Digital signals have discrete values, whereas analog
signals have continuous values. 3 The signal's independent variable may be
space (pictures), time (speech, for instance), or integers (denoting the
sequencing of letters and numbers in the football score).
a. Signals in Analog
Your vocal cords excite acoustic resonances in your vocal tract to
produce analog signals, which are typically specified over continuous
independent Analog and Digital Signals in Electrical Engineering
variable(s). The speech signal thus corresponds to a function with
independent variables of space and time and a value corresponding to air
pressure, as the consequence is pressure waves traveling in the air: S (x, t)
In this case, spatial coordinates are indicated by the vector notation x.
You are analyzing the voice signal at a specific spatial point, let's say x0,
while you record someone speaking.
Photographs are continuous-valued signals that are defined over space
and are static. The optical reflection qualities of black and white images
are limited to a single value at each point in space.
Reflectivity's dependence on the optical spectrum is expressed by the
values in color photographs. Painters discovered long ago that combining
the so-called fundamental colors—yellow, blue, and red—could create
incredibly lifelike color images. Therefore, a separate set of colors is
utilized in images, which are typically thought of as having three values
at every point in space: How much blue, green, and red are there? Color

signal is just a function. Digital signals have discrete values, whereas analog
signals have continuous values. 3 The signal's independent variable may be
space (pictures), time (speech, for instance), or integers (denoting the
sequencing of letters and numbers in the football score).
a. Signals in Analog
Your vocal cords excite acoustic resonances in your vocal tract to
produce analog signals, which are typically specified over continuous
independent Analog and Digital Signals in Electrical Engineering
variable(s). The speech signal thus corresponds to a function with
independent variables of space and time and a value corresponding to air
pressure, as the consequence is pressure waves traveling in the air: S (x, t)
In this case, spatial coordinates are indicated by the vector notation x.
You are analyzing the voice signal at a specific spatial point, let's say x0,
while you record someone speaking.
Photographs are continuous-valued signals that are defined over space
and are static. The optical reflection qualities of black and white images
are limited to a single value at each point in space.
Reflectivity's dependence on the optical spectrum is expressed by the
values in color photographs. Painters discovered long ago that combining
the so-called fundamental colors—yellow, blue, and red—could create
incredibly lifelike color images. Therefore, a separate set of colors is
utilized in images, which are typically thought of as having three values
at every point in space: How much blue, green, and red are there? Color
images are multivalued vector-valued signals in mathematics: s (x)=(r
(x),g (x),b (x)) T.
b. There are several intriguing examples where the analog signal is
dependent on a discrete variable rather than a continuous one, like time.
For instance, hourly temperature data exhibit continuous analog values,
but the integers are (basically) the signal's independent variable.
Signals in Digital Form
The term "digital" denotes a discrete-valued signal with an independent
variable of integer value. Digital data contains both symbols and numbers
(characters typed on the keyboard, for example). For information
manipulation and transformation, computers rely on digital
representations. Each symbol is represented by a distinct integer and has
no numerical value. A seven-bit integer is used to represent the capital
and lowercase letters, digits, punctuation, and other symbols in the ASCII
character code. For instance, the letter A is represented by the number 65
in the ASCII code, and the letter a by the number 97.
