Abstract A generalized time domain approach is described for the analysis and design of wave digital filters capable of performing sampling rate alterations whether integer or non‐integer. It is based on sequential computation of the filter's system response; then this discrete response is reduced to a rational function form. the proposed approach is characterized by its simplicity as well as its ability to analyse and design multistage, multirate wave digital structures. Illustrative examples are also given.
