Oscillator is an electronic circuit that produces a repetitive electronic signal (sine wave or square wave). Some examples of signal generated by oscillators includes signal broadcast by radio and TV transmissions, clock signals and sound produced by electronic beeper and video games.
Phase shift oscillator
An oscillator circuit which uses RC network as a combination of resistors and capacitors for its frequency selective parts is called RC oscillator. Phase shift oscillator is an electronic oscillator which has inverting amplifier and a feedback filter which shifts the phase of the amplifier output by 180 degree at the oscillation frequency.
- Oscillators converts DC signals into AC signal.
- Oscillator generates pulse type output along with square, saw-tooth and sine wave.
