Logic signal

英语百科

Digital signal

A received digital signal may be impaired by noise and distortions without necessarily affecting the digits
In signal processing, a digital signal is an abstraction that is discrete in time and amplitude, meaning it only exists at certain time instants.
A frequency shift keying (FSK) signal is alternating between two waveforms, and allows passband transmission. It is considered digital in literature on data transmission.

A digital signal is a signal that represents a sequence of discrete values. A logic signal is a digital signal with only two possible values, and describes an arbitrary bit stream. Other types of digital signals can represent three-valued logic or higher valued logics.
