Quizplus · Accepted Answer

A digital signal is a sequence of discrete voltage pulses that represent digital data. It can be transmitted over a wire medium and is less prone to interference and distortion compared to analog signals. Audio and text signals are examples of digital data that can be transmitted using digital signals; however, they are not signals themselves. Analog signals, on the other hand, are continuous waveforms that can be affected by noise and distortion during transmission over a wire medium.
