N, then a nondistorted pulse amplitude at the sampling instant is pre served. one class of such a filter that is most often used in digital communication systems is the so called raised cosine filter. the amplitude characteristic of such a filter for impulse transmission, h im (f), consists of a flat portion followed by a roll off. Chapter 5: digital transmission of analog signals. 5.1 introduction. the trend in the design of new communication systems has been toward increasing the use of digital techniques. digital communications offer several important advantages compared to analog communications, for example, higher performance, greater versatility, and higher security.
