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
Modulation — For musical change of key, see Modulation (music). For other uses, see Modulation (disambiguation). Passband modulation v · d · e … Wikipedia
Amplitude-shift keying — (ASK) is a form of modulation that represents digital data as variations in the amplitude of a carrier wave.The amplitude of an analog carrier signal varies in accordance with the bit stream (modulating signal), keeping frequency and phase… … Wikipedia

Modulation error ratio — The modulation error ratio or MER is a measure used to quantify the performance of a digital radio transmitter or receiver in a communications system using digital modulation (such as QAM). A signal sent by an ideal transmitter or received by a… … Wikipedia
Amplitude-companded single-sideband modulation — ACSSB (amplitude companded single sideband) is a narrowband modulation method using a single sideband with a pilot tone, allowing an expander in the receiver to restore the amplitude that was severely compressed by the transmitter. This mode… … Wikipedia
Superheterodyne receiver — A 5 tube superheterodyne receiver made in Japan around 1955 In electronics, a superheterodyne receiver (sometimes shortened to superhet) uses frequency mixing or heterodyning to convert a received signal to a fixed intermediate frequency, which… … Wikipedia
Single-sideband modulation — (SSB) is a refinement of amplitude modulation that more efficiently uses electrical power and bandwidth. It is closely related to vestigial sideband modulation (VSB) (see below).Amplitude modulation produces a modulated output signal that has… … Wikipedia
