Group delay and phase delay — Group delay is a measure of the time delay of the amplitude envelopes of the various sinusoidal components of a signal through a device under test, and is a function of frequency for each component. Phase delay is a similar measure of the time… … Wikipedia
Phase (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 … Wikipedia
Time-Domain Thermoreflectance — is a method by which the thermal properties of a material can be measured, most importantly thermal conductivity. This method can be applied most notably to thin film materials (up to hundreds of nanometers thick), which have properties that vary … 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-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 shift module — A phase shifter is a microwave network which provides a controllable phase shift of the RF signal [Microwave Solid State Circuit Design, 2nd Ed., by Inder Bahl and Prakash Bhartia, John Wiley Sons, 2003 (Chapter 12)] [RF MEMS Theory, Design and… … 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
