Lock-in amplifier — A lock in amplifier (also known as a phase sensitive detector) is a type of amplifier that can extract a signal with a known carrier wave from extremely noisy environment (S/N ratio can be as low as 60 dB or even lessFact|date=December 2007). It… … 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
