Abstract : Signal flow graph techniques were developed for the analysis of modulo-m linear sequential circuits and of mixed systems containing both modulo-m adders and adders of real numbers. One of the main results is the proof that the rational generating function of a modulo-m linear sequential circuit can be obtained from the generating function of a topologically similar sampled data system (with integer branch gains) by simply replacing each integer valued coefficient in the latter generating function by its (mod m) equivalent. Besides the direct application to the analysis of modulo m sequential circuits and sequence generators, mixed systems which arise in the partial response signaling format for digital data transmission were also investigated.
