  • 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

  • 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

  • Keying (telecommunications) — Keying is the shaping of a signal to convey information, known as modulation. Modulation can be used to represent a digital message as an analogue waveform. This is known as keying and several keying techniques exist (these include phase shift… …   Wikipedia
