Encyclopedic overview

A binary signal, also known as a logic signal, is a digital signal with two distinguishable levels

A digital signal is a signal that represents data as a sequence of discrete values; at any given time it can only take on, at most, one of a finite number of values. This contrasts with an analog signal, which represents continuous values; at any given time it represents a real number within an infinite set of values.
