Solution

In amplitude modulation, the amplitude of the carrier wave signal is varied in accordance with the information signal. We do amplitude modulation of a signal wave by superimposing it with a carrier signal. At the receiver, the signal is then demodulated by removing the carrier signal and the original data is obtained again at the receiver end.
