• 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

• Quadrature filter — In signal processing, a quadrature filter q(t) is the analytic representation of the impulse response f(t) of a real valued filter::q(t) = f {a}(t) = left(delta(t) + {i over pi t} ight) * f(t)If the quadrature filter q(t) is applied to a signal… …   Wikipedia
