Vedclass · Answer

(A) An oscillator is an electronic circuit that produces a periodic,oscillating electronic signal,often a sine wave or a square wave. It functions as an amplifier with $positive$ $feedback$. In a positive feedback system,a portion of the output signal is fed back to the input in phase with the input signal,which sustains the oscillations. Therefore,an oscillator is essentially an amplifier with positive feedback.

An oscillator is which of the following types of amplifier?
