$PWM$

Vedclass · Answer

(C) In Pulse Width Modulation $(PWM)$,the width (or duration) of the pulses is varied in accordance with the instantaneous amplitude of the modulating signal.Pulse Amplitude Modulation $(PAM)$ involves varying the amplitude of the pulses.Pulse Position Modulation $(PPM)$ involves varying the position of the pulses in time.Pulse Code Modulation $(PCM)$ involves converting the analog signal into a digital code.Therefore,the correct option is $PWM$.

In a modulation process where the pulse duration varies with the modulating signal,it is called ......
