P.23 Know gaps

Oscillators- An electronic oscillator is an electronic circuit that produces a

repetitive electronic signal, often a sine wave or a square wave. They are

widely used in innumerable electronic devices. Common examples of signals

generated by oscillators include signals broadcast by radio and television

transmitters, clock signals that regulate computers and quartz clocks, and

the sounds produced by electronic beepers and video games. There are

different types of oscillators such as phase Shift Oscillator, Wein Bridge

Oscillator,Tuned Oscillator, Colpitts Oscillator, Hartley Oscillator,

Quartz Crystal Oscillator.

Rectifiers are the largest class of products in the diode family. They are

primarily used for blocking in one direction and conducting in the other.

These include General Purpose, Standard, Fast, UltraFast, Signal/ Switching,

High-voltage and Schottky. Because of their predominant rectifying qualities,

they are primarily used for power or signal conditioning in a variety of

applications.-.
