Electronics Discussion

In your own words, describe

1. The Wien Bridge Oscillator
2. The tuned oscillator
3. The Crystal oscillator
4. The unijunction transistor oscillator

Power supplies (regulators) are one of the most important devices used in the electronics. A power supply or regulator provides a constant dc output voltage that is independent of the input voltage, output load current, and temperature.

1. Describe in your own words the stages of a power supply.
2. What is the function of the transformer, the rectifier, the filter?
3. What is the difference between a linear and a switching power supplies? Could you describe some applications of each?
