Phase 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.… … 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
Frequency modulation synthesis — In audio and music frequency modulation synthesis (or FM synthesis) is a form of audio synthesis where the timbre of a simple waveform is changed by frequency modulating it with a modulating frequency that is also in the audio range, resulting in … 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 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

Minimum phase — In control theory and signal processing, a linear, time invariant system is said to be minimum phase if the system and its inverse are causal and stable.[1][2] For example, a discrete time system with rational transfer function H(z) can only… … Wikipedia
Quasi-phase-matching — is a technique in nonlinear optics which allows a positive net flow of energy from the pump frequency to the signal and idler frequencies by creating a periodic structure in the nonlinear medium. Momentum is conserved, as is necessary for phase… … Wikipedia
Utility frequency — The waveform of 230 volt, 50 Hz compared with 110 V, 60 Hz. The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the frequency at which alternating current (ac, also AC) is transmitted from a… … Wikipedia
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
