When the output of an amplifier fluctuates in phase, even though the input does not, the circuit introduces phase distortion into the signal
Changes in desired picture color caused by shifts in chroma phase.
Also called phase shift and sometimes group delay, it results when one part of the frequency spectrum is delayed more than another. Phase shifts can cause test waveforms viewed on an oscilloscope to distort but must be fairly extreme if they are to be audible when listening to music under normal home-playback conditions, at least with loudspeakers.
A type of audible distortion caused by time delay between various parts of the signal.
The distortion that occurs in an instrument when the relative phases of the input signal differ from those of the output signal.
A distortion of the phase component of a signal. This occurs when the phase shift of an amplifier is not proportional to frequency over the design bandwidth.
Phase distortion is distortion that occurs when (a) the phase-frequency characteristic is not linear over the frequency range of interest, i.e., the phase shift introduced by a circuit or device is not directly proportional to frequency, or (b) the zero-frequency intercept of the phase-frequency characteristic is not 0 or an integral multiple of 2Ï€ radians.
