Question

Quizplus · Accepted Answer

An analog signal is a continuously varying electromagnetic wave that can be propagated over a variety of media, including wire media and fiber optic cable. Digital signals, on the other hand, are discrete and non-continuous. Periodic and aperiodic signals describe the repetitive or non-repetitive nature of a signal's waveform, respectively, and are not relevant to the propagation media.
