Abstract

In the communication systems, many information bearing signals are transmitted by service type of carrier modulation. The channel over which the signal is transmitted is limited in bandwidth to an interval of frequencies centered at the carrier as in the double side-band modulation techniques, Fig.1.13b, or adjacent to the carrier as in the single side-band modulation techniques, Fig.9.1a,b.
