wave phase
61Phase space method — In applied mathematics, the phase space method is a technique for constructing and analyzing solutions of dynamical systems, that is, solving time dependent differential equations. The method consists of first rewriting the equations as a system… …
62phase — /feɪz / (say fayz) noun 1. any of the appearances or aspects in which a thing of varying modes or conditions manifests itself to the eye or mind. 2. a stage of change or development. 3. Astronomy a. the particular appearance presented by a planet …
63Phase — Alternating current is carried by conductors and a ground to residential, commercial, or industrial consumers. The waveform of the phase power appears as a single continuous sine wave at the system frequency whose amplitude is the rated voltage …
64phase distortion — noun : change of wave form of a composite wave due to change of relative phase of its component harmonics …
65Phase 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 …
66phase velocity — noun : the velocity of a wave motion as determined by the product of the wavelength and frequency called also wave velocity; compare group velocity, particle velocity * * * Physics. the velocity with which a simple harmonic wave is propagated,… …
67phase-shift keying — noun A form of phase modulation in which digital information is transmitted through discrete changes of the phase of a carrier wave. Syn: PSK …
68phase modulation — noun A method of sending information by modifying (modulating) the difference in phase (fraction of a wave length) between a signal and a reference. See Also: phase modulator …
69phase modulator — noun an electronic circuit that causes the phase angle of a modulated wave to vary in accordance with the modulating signal See Also: phase modulation …
70Phase shift — F/A/V The displacement of a waveform in time. Some electrical components introduce phase shift into a signal. When various frequencies are displaced differently, distortion occurs. Electrical cancellation may occur when two equal signals are out… …
