Amplitude and phase-shift keying — or Asymmetric Phase shift keying, (APSK), is a digital modulation scheme that conveys data by changing, or modulating, both the amplitude and the phase of a reference signal (the carrier wave). In other words, it combines both Amplitude shift… … 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
Very minimum-shift keying — VMSK, for Very Minimum Shift Keying modulation, is one of several digital modulation methods claimed to send high speed digital data through very low bandwidth (or narrowband) channels. A typical claim is a data rate of 6 Mbit/s in a bandwidth of … Wikipedia

PSK — Phase Shift Keying. In this method of modulation/demodulation, there are two frequencies used (usually 1200 Hertz and 2400 Hertz). There are 4 different phase angles (0, 90, 180, and 270 degrees), representing dibits 00, 01, 10, and 11. This is… … Dictionary of telecommunications
