ABSTRACT
Characteristics of linear systems are described by the system's impulse response, as administrated by the mathematics of convolution. The important of the impulse response is because of its uses in many practical aspects, as echo suppression in long-distance telephone calls. This chapter describes the properties of one of the most common applications of impulse response called convolution. First, several conventional coevolution methods discussed. Second, it will be presented dealing with cascade and parallel combinations of linear systems. Third, the technique of correlation will introduce. Fourth, a different problem with convolution examined.
