• Phase distortion — In signal processing, phase distortion or phase frequency distortion is distortion that occurs when (a) a filter s phase response is not linear over the frequency range of interest, that is, the phase shift introduced by a circuit or device is… …   Wikipedia

• Frequency — For other uses, see Frequency (disambiguation). Three cyclically flashing lights, from lowest frequency (top) to highest frequency (bottom). f is the frequency in hertz (Hz), meaning the number of cycles per second. T is the period in seconds (s) …   Wikipedia

• Phase response — is the relationship between the phase of a sinusoidal input and the output signal passing through any device which accepts input and produces an output signal such as an amplifier or a filter.Amplifiers, filters and other devices are often… …   Wikipedia

• Phase response curve — A phase response curve (PRC) illustrates the transient change in the cycle period of an oscillation induced by a perturbation as a function of the phase at which it is received. PRCs are used in various fields; examples of biological oscillations …   Wikipedia

• Phase margin — In electronic amplifiers, phase margin is the difference, measured in degrees, between the phase of the amplifier s output signal and 360°. In feedback amplifiers, the phase margin is measured at the frequency at which the open loop voltage gain… …   Wikipedia
