c) AM
d) PAM

Correct Answer: c.) AM


Analog communication is a type of communication in which the message to be transmitted is analog in nature. Here the message signal modulates a high frequency carrier signal. A continuous wave signal is defined continuously in time domain. However if the signal is defined at discrete times, the signal is a discrete signal.
