Digital pulse modulation permits the use of regenerative repeaters, when placed along the transmission path at short enough distances, can practically eliminate the degrading effects of channel noise and signal distortion. . nalhareqi-2013. 1. Standard Amplitude Modulation (AM). nalhareqi-2013. 2. In the DSP-SC demodulation, a receiver must generate a local carrier in frequency and phase synchronism with the carrier used for modulation..

Phase modulation (PM). PCM is a method of converting an analog signal into a digital signal. (A/D conversion). The amplitude of Analog signal can take any value over a continuous range i.e. it can take on an infinite values..
