Pulse code modulation

Vedclass · Answer

(B) In communication systems,modulation techniques are categorized based on how the signal is processed. Pulse amplitude modulation $(PAM)$,pulse width modulation $(PWM)$,and pulse position modulation $(PPM)$ are all examples of analog pulse modulation because the amplitude,width,or position of the pulses varies continuously with the analog signal. Pulse code modulation $(PCM)$ involves sampling an analog signal and then quantizing and encoding the samples into a binary format (a sequence of $0$s and $1$s). Since $PCM$ represents information in discrete binary form,it is classified as a digital system. Therefore,the correct option is $B$.

Indicate which one of the following systems is digital.
