Phase fired controllers — Phase control (PFC), also called phase cutting, is a method of pulse width modulation (PWM) for power limiting, applied to AC voltages. It works by modulating a thyristor, SCR, triac, thyratron, or other such gated diode like devices into and out … 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 offset modulation — works by overlaying two instances of a periodic waveform on top of each other. (For the purposes of softsynths, the waveform is usually generated by using a lookup table.) The two instances of the waveform are kept slightly out of sync with each… … Wikipedia
