Digital Signal Definition/Meaning:

A waveform or signal whose voltage at any particular time will be at any one of a group of discrete levels, generally two; a two-level signal is sometimes called a binary digital signal or binary signal. In binary logic circuits, in which only two discrete voltage levels are used, one level will correspond to logic 1 (true), usually the high level, and the other will correspond to logic 0 (false).
