Binary signalling formats
A logic signal waveform: For other uses, see Digital signal disambiguation. Logic changes are triggered either by the rising edge or the falling edge.

In digital radio schemes one or more carrier waves are amplitude or frequency or phase modulated with a signal to produce a digital signal suitable for transmission. In binary signalling formats digital circuitsthe signal can have two possible values; this is called a binary signal or logic signal. This process is the basis of synchronous logicand the system is also used in digital signal processing.
A logic signal waveform: A threshold is designed for each logic family. A digital signal is an abstraction which is discrete binary signalling formats time and amplitude. In communications, sources of interference are usually present, and noise is frequently a significant problem.
In computer architecture and other digital systems, a waveform that switches between two voltage levels or less commonly, other waveforms representing the two states of a Boolean value 0 and 1, or Low and High, or false and true is referred to as a digital signal or logic signal or binary signal when it is interpreted in terms of only two possible digits. Because of this discretizationrelatively small changes to the analog binary signalling formats levels do not leave the discrete envelope, and as a result are ignored by signal state sensing circuitry. Often digital signals are "sampled" by a clock signal at regular intervals binary signalling formats passing the signal through an "edge sensitive" flip-flop.
When this is done the input is measured at those points in time, and the signal from that time is passed through to the output and the output is then held steady till the next clock. When below that threshold, the signal is lowwhen above high.
