Quadrature phase — Communication signals often have the form::A(t)cdot sin [2pi ft + phi(t)] , which is called envelope and phase form.An equivalent representation, called quadrature carrier form, is::I(t)cdot sin(2pi ft) + Q(t)cdot underbrace{cos(2pi ft)}… … Wikipedia

Quadrature amplitude modulation — (QAM) (Pronounced IPA|kwa:m) is a modulation scheme which conveys data by changing ( modulating ) the amplitude of two carrier waves. These two waves, usually sinusoids, are out of phase with each other by 90° and are thus called quadrature… … 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
Quadrature booster — A quadrature booster, also known as a phase shifting transformer or more simply a quad booster, is a specialised form of transformer used to control the flow of real power on three phase electricity transmission networks. For an alternating… … Wikipedia
