Vedclass · Answer

(B) In amplitude modulation,we have three main components:$1$. Information signal (or modulating signal): This is a low-frequency signal that carries the information. In the figure,Signal $A$ represents this low-frequency wave.$2$. Carrier wave: This is a high-frequency sinusoidal wave. In the figure,Signal $B$ represents this high-frequency wave.$3$. Amplitude modulated wave: This is the result of superimposing the information signal onto the carrier wave,where the amplitude of the carrier wave varies according to the instantaneous amplitude of the information signal. In the figure,Signal $C$ represents this modulated wave.Therefore,Signal $A$ is the information message and Signal $C$ is the amplitude modulated wave.

Three signals related to amplitude modulation are shown in the figure. The correct assignment of the signals is
