Digital filter analysis using IBM PC's

A computer program is presented for analyzing digital\ud filters with arbitrary topology. The input data is similar\ud to that of the SPICE program for analog circuit\ud analysis. The digital filter analysis program is designed\ud to be used on IBM compatible personal computers with\ud graphics capability. It is especially well suited for\ud educational purposes. The program prompts the user so that\ud an instruction manual is not required. Several filter\ud analysis examples are also included. A portion of this work\ud was presented at the IEEE conference described in
