How far a periodic function is horizontally from the usual position. See: Periodic Function. Amplitude, Period, Frequency and Phase Shift.
In signal processing, linear phase is a property of a filter where the phase response of the filter is a linear function of frequency. The result is that all frequency components of the input signal are shifted in time (usually delayed) by the same constant amount (the slope of the linear function), which is referred to as the group delay. Consequently, there is no phase distortion due to the time delay of frequencies relative to one another. Nettet1. sep. 2016 · An ideal linear-phase filter, then, exhibits phase shift that increases linearly with frequency, and it thereby provides constant temporal delay (this applies primarily to the frequencies within the …
