Distortion occurring in a system, subsystem, or device when the output amplitude is not a linear function of the input amplitude under specified conditions. Note: Amplitude distortion is measured with the system operating under steady-state conditions with a sinusoidal input signal. When other frequencies are present, the term "amplitude" refers to that of the fundamental only.

Distortion of motion video potentially observable by the viewer. In some instances, the distortion becomes more observable with increased motion. The distortion may appear as smearing, block distortion, jerkiness, or other impairments.
Industry:Telecommunications
Distortion resulting from causes generally subject to laws concerning random occurrences.
Industry:Telecommunications
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 2 radians. Synonym phase-frequency distortion.
