In modulation, the sound wave is electrically impressed on an (a)   wave.

(a)   is the process of manipulating the amplitude, the frequency, or the phase of a carrier wave in response to an incoming voice, video, or data signal.

When the amplitude of a high frequency carrier wave is changed in accordance with the intensity of the signal, it is called the (a)   modulation.

In the (a)   modulation, only the amplitude of the carrier wave is changed.

In amplitude modulation, the amplitude of the carrier wave is changed in accordance with the (a)   of the signal.
