WebApr 21, 2006 · The simplest is called binary phase-shift keying (BPSK), which uses two opposite signal phases (0i – 180i) to encode bits. For example, the phase shift could be 0i for encoding a “0,” and 180i for “1,” or the phase shift could be -90 for 0 and +90i for a 1. In either case, the representation of 0 and 1 are a total of 180i apart. WebBinary amplitude shift keying (ASK) keys the carrier frequency as one of two discrete levels during the bit time T b for the representation of binary logic signals for the transmission of information. A convenient set of amplitudes for binary ASK is 1 V for binary 1 and 0 V for binary 0, which is also known as on-off keying (OOK).
