Phase modulation (PM). 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, . Wayne Maxwell. Martin Cacan. Christopher . Haile.

Pulse code modulation (PCM) is essentially analog-to-digital conversion of a special type where the . information . Audio/video signals are . analog. in nature. Analog signals can take . infinite. number of values. Hence more difficult to detect at receiver after noise corruption. PCM converts analog signals to digital pulses.
