signal
signal
1. A form of data that is usually envisaged as a sequence of values of a scalar quantity – the amplitude – recorded (i.e. measured, tabulated, or plotted) against time. The amplitude is most often, but by no means always, an electric potential. For example, if the signal is a sine wave with a mean value of zero (symmetrical about zero volts), then the amplitude is the value of the peak voltage. See also discrete and continuous systems, space domain.
2. Any path transmitting some data or function. See also control signal.
3. To convey data or control information from one point to another.
