Q. Amplitude modulation is the process of

Solution:

Modulation is the phenomenon of superimposing a low audio frequency information signals (called the modulation signals) on a high-frequency wave (called, the carrier wave). When we modulate the amplitude of the carrier wave to transmit the information, it is known as amplitude modulation.
