WebApr 21, 2006 · Phase-shift keying (PSK) is a method of digital communication in which the phase of a signal is varied in order to transmit information. There are several methods that can be used to accomplish PSK. The simplest is called binary phase-shift keying (BPSK), which uses two opposite signal phases (0i – 180i) to encode bits. WebIntroduction. 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 constant. The level of amplitude can be used to represent.
