What is 8 phase shift keying?
8 phase shift keying is a complex form of digital modulation by altering a sine wave and a cosine wave: shifting their phase. The best explanations I have found so far can be found at http://en.wikipedia.org/wiki/Phase-shift_keying and http... Read More »

What is phase-shift keying?
( ′fāz ¦shift ′kē·iŋ ) (communications) A form of phase modulation in which the modulating function shifts the instantaneous phase of the modulated wave between predetermined discrete values. Abbreviated PSK. Read More »
