Vedclass · Answer

(B) An analog signal is a continuous signal that varies with time. In the given figure,signal $A$ (sinusoidal wave) and signal $C$ (sawtooth wave) vary continuously with time,hence they are analog signals.$A$ digital signal is a discrete signal that takes only two levels (usually $0$ and $1$). In the given figure,signal $B$ is a square wave that switches between two discrete levels,hence it is a digital signal.Therefore,$A$ and $C$ are analog signals and $B$ is a digital signal.

The time variations of signals $A, B$ and $C$ are shown below. Choose the correct statement.
