in-phase signals
1Phase switch — A phase switch is a device used to increase the discrimination and sensitivity of an interferometer, especially at radio frequencies; an extra half wave path difference is switched in, at well defined frequency, between the two interfering signal …
2Phase synchronization — is the process by which two or more cyclic signals tend to oscillate with a repeating sequence of relative phase angles.Phase synchronisation is usually applied to two waveforms of the same frequency with identical phase angles with each cycle.… …
3Phase (waves) — Phase in waves is the fraction of a wave cycle which has elapsed relative to an arbitrary point.[1] Contents 1 Formula 2 Phase shift 3 Phase difference …
4Phase modulation — (PM) is a form of modulation that represents information as variations in the instantaneous phase of a carrier wave.Unlike its more popular counterpart, frequency modulation (FM), PM is not very widely used. This is because it tends to require… …
5Phase 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… …
6Phase-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… …
7Phase-shift keying — Passband modulation v · d · e Analog modulation AM · …
8Phase Alternating Line — Das Phase Alternation Line Verfahren [feɪz ˈɒltəneɪʃən laɪn], kurz PAL, ist ein Verfahren zur Farbübertragung beim analogen Fernsehen. Es wurde mit dem Ziel entwickelt, störende Farbton Fehler, die im NTSC Verfahren nur manuell und unbefriedigend …
9Phase 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… …
10Phase 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… …
