Phase detector — A phase detector is a frequency mixer or analog multiplier circuit that generates a voltage signal which represents the difference in phase between two signal inputs. It is an essential element of the phase locked loop (PLL).Detecting phase… … Wikipedia
Zero crossing — is a commonly used term in electronics, mathematics, and image processing. In mathematical terms, zero crossing basically means the changing of sign (e.g. from positive to negative), that is represented with a crossing of the axis (zero value) in … Wikipedia
Phase noise — is the frequency domain representation of rapid, short term, random fluctuations in the phase of a wave, caused by time domain instabilities ( jitter ). Generally speaking radio frequency engineers speak of the phase noise of an oscillator,… … Wikipedia
Phase-locked loop — PLL redirects here. For other uses, see PLL (disambiguation). A phase locked loop or phase lock loop (PLL) is a control system that generates an output signal whose phase is related to the phase of an input reference signal. It is an electronic… … Wikipedia
Phase inversion — A phase inversion is the introduction of a phase difference of 180° into a waveform. As such, it is more properly called a polarity inversion, as phase can differ relative to frequency but polarity is absolute.For example, in a push pull power… … Wikipedia
Signal-to-noise ratio — For signal to noise ratio in statistics, see Cohen s d. Signal to noise ratio (often abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. It is defined… … Wikipedia
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
Return-to-zero — (RZ) describes a line code used in telecommunications signals in which the signal drops (returns) to zero between each pulse. This takes place even if a number of consecutive 0 s or 1 s occur in the signal. The signal is self clocking. This means … Wikipedia
