Module Learning Outcomes
|
|
1. Apply electric circuit analysis techniques. |
|
3. Design and construct digital or analogue circuits. |
|
5. Explain the behaviour semiconductors. |
|
6. Use computer aided simulation software to implement and simulate electrical and digital circuits. |
Part A: Semiconductor Devices, LO 5,6 [10 marks]
Using myDAQ device, you are required to build a hardware circuit used to convert alternating voltage to pulsating direct voltage using semiconductor diodes. This circuit is called half wave rectifier. Figure 1 displays a similar circuit.
Figure 1: Half wave rectifier circuit
1. Build the circuit in Figure 1 (Small breadboard will be provided) and present it to your tutor during your face-to-face viva.
2. Choose the input frequency to be your last three digits of your SID.
3. Insert clearly labelled screenshots of your hardware circuit and produce a graph showing the voltage across the load resistor.
4. Explain the produced graph and steps you followed to accomplish it. This should prove your ownership of the design and understanding of the functions of MyDaq kit.
5. Use the assignment template provided.
Part B: Digital Circuits LO 3,6 [75 marks]
You are required to design, simulate and construct a keypad controlled decimal-to-BCD encoder connected to a common anode seven segment LED display. The full circuit diagram of the project is given in Figure 2 below.
Figure 2: Circuit diagram illustrating the use of an encoder and a decoder to drive a 7-segment LED display via a 0-to-9 keypad
In addition, you will be required to produce a 1500 word technical report based on the design, build and test.
As part of the assignment, you will be required to complete the following tasks:
1. Draw and simulate the circuit diagram given above (Figure 2) using NI Multisim.
· Save the file as yourSID_7segment and upload a copy of the file to Moodle (Link will be provided by your Tutor).
· The file should be executable by your tutor.
·
2. Build Figure 2 neatly on the large breadboard using the following components available in the lab:
· Nine push buttons,
· Nine 10kΩ resistors,
· One CD74HC147E integrated circuit (it is the CD74HC147 in Figure 2),
· One SN74HC04N integrated circuit (containing the NOT gates),
· One SN74LS47N integrated circuit (it is the SN7447A in Figure 2),
· Seven 330Ω resistors,
· One common anode 7 segment display,
· Wires.
Use the components datasheets available on Moodle to understand how to connect the components.
3. Redesign and simulate using NI Multisim a BCD(binary coded decimal) to seven segment decoder IC to show your SID:
· The decoder should be able to drive the 7 segment to display “0” when no button is pressed. If Push Button1 (PB1) is pressed, the 7-segment displays your first ID digit and so on from left to right as stated in table 1.

4. From the specification of the circuit:
· Determine the required number of inputs and outputs and assign a symbol to each input and output.
· Derive a truth table that defines the relationship between the inputs and the outputs.
· Using Karnaugh maps, derive a simplified Boolean function for each of the input variables.
· Draw the logic diagram of the simplified circuit using Multisim.
5. Replace the SN7447 IC in the Multisim file (yourSID_7segment) with the simplified logic circuit you designed in task 3 above and simulate the circuit. Save it as yourSID_D7segment and upload a copy of the file to Moodle (link is provided by your tutor).
6. In your report, discuss the steps you have followed to accomplished tasks 1, 2, 3, 4 and 5 respectively (as specified above). Include screenshots of the simulations and the design process in your report.
7. You are required to present Part A and B to your tutor in a form of oral assessment. Your tutor will be asking you question that tests your depth of understanding on the taught subject.
Part C: AC circuits LO1, 6 [15 Marks]
The circuit in figure 3 shows a series resonant circuit.
Vin is 20 V r.m.s, choose the value of L1 to be the last non-zero digit of your student ID (eg. If your student ID is 7256105, then L1 =5mH).
Simulating the circuit in Figure 3 on Multisim.
i. Plot the frequency response of the circuit.
ii. Indicate clearly its characteristics (ie. f1, f2, fr)

Guidance notes and considerations
You will be graded on the following aspects of the project:
· Implementation Part A and B
Your project will be assessed on how effective the concept was implemented on hardware. The focus will be on the quality of the work, the finished appearance and its performance during the demonstration. You will be asked some questions on your finalised hardware. You will be informed about the date by your tutor.
· Design
You will be assessed on your ability to produce a simplified design and correctly simulate the project using Multisim software. Please refer to the assignment template.
· Final report
You will be assessed on the quality of the report of the system designed and the simulation. A key feature will be how easily it would be for someone else to understand, reproduce or modify your project by following your report.
Always consider the following: What, when, why, where and how in developing your assignments. These will assist you to analyse, evaluate and reason your points of view. Remember to support your concept / academic argument with an example as it allows the reader to appreciate the rigour and your understanding of the task.
Note that you will be marked also against your reflection and critical analysis, knowledge and understanding, evidence of reading, referencing & bibliography and presentation &grammar& spelling.
Guideline for the report outline:
Make sure you follow the Assessment template on Moodle.

Plagiarism avoidance:
Recommended Referencing Practice - Citations and Quotations
In order to avoid submitting any sections which may contain “plagiarism” or “poor academic practice” or “collusion” it is important that students should adopt the following referencing practice:
CITATIONS: Include an in-text citation (author and year of publication) and give the correct reference at the end of the work for any sources used or referred to or paraphrased in the work but not directly quoted.
QUOTATIONS: Mark up any directly quoted text using “quotation marks” (this enables Turnitin to identify “quoted” sections), add an in-text reference (author, year of publication and page number) and include the correctly formatted reference at the end of the work;
Examples of “plagiarism” or “poor academic practice” or “collusion”: a. Excessive and inappropriate use of quotations.
e.g. Where the assessment learning objectives require a student to explain an argument but the student simply copies an explanation from another source, correctly annotating the work as a quotation. b. Quoted sections that are not correctly annotated as quotations (using quotation marks, which will allow Turnitin to identify quoted sections), but where there is an attempt to cite and reference the source. e.g. If a student includes separate paragraphs in the format “In 2005 Smith found evidence that…” and then copies the rest of the paragraph directly from the cited source.
c. Copying material from another source without indicating it is a quotation (indicated by using quotation marks, which will allow Turnitin to identify quoted sections). d. Omitting from the reference list and/or bibliography at the end of a submission any sources that a student has used to help formulate their own answer, even if the actual submission is written in the student’s own words. e. The use of substantial sections of text that have been previously written by others, but with no clear indication that the text is not the student’s own work. f. Copied sections of text from elsewhere without the source and extent of the copied section being clearly indicated in the text of the assignment.
g. Directly copied sections, such as several complete paragraphs, without in-text acknowledgement of the sources used.
h. Collusion e.g. two or more students with similar or identical work, or with large sections of work that are similar or identical in their individual submissions. This can apply to submissions from students studying at the same or different institutions regardless of the dates of submission.
