Abstract :
In the paper, a method for optimal design of class 1 partial response filters with low intersymbol interference (ISI) is described. The filter selectivity and stopband attenuation can be easily specified or controlled. It is shown that ISI can be reduced by introducing rolloff around the Nyquist frequency at the expense of a small increase in spectral inefficiency. Class 4 partial response signals are obtained by using class 1 partial response filters. Design examples are given to show that the design method is appropriate for applications
