Lecture Learning Outcomes. Be able to understand, appreciate and differentiate the different signal encoding criteria available.. Class Contents. Signal Encoding Criteria. Digital Data, Analogue Signals. In coherent phase shift keying different phase modulation schemes will be covered i.e. binary PSK, quadrature phase shift keying and M-. ary. PSK . Binary PSK will be studied in the next slides. 1. Binary Phase shift keying. 1. Introduction. A digital signal is superior to an analog signal because it is more robust to noise and can easily be recovered, corrected and amplified. For this reason, the tendency today is to change an analog signal to digital data. In this section we describe two techniques, . By Amir . Taherin. Eng. M. . Zamanian. Contents. Definition. 1.
