Analog signals represent data as continuous waves, while digital signals use discrete binary values (0s and 1s).
Analog Signal vs. Digital Signal

Key Differences

An analog signal is a continuous signal that varies over time, representing physical measurements. Digital signals, in contrast, use binary code (0s and 1s) and are non-continuous.
