phase - Computer Definition
In a periodic function such as the cyclic variation of an electromagnetic waveform, a relative measurement that describes the relationship between the positions of a signal at two instants in time. In other words, phase is a measurement of the relative position of a waveform at a significant instant of the signal relative to a time scale. Phase is measured in degrees (
