MAPLE program as a Tool for Symbolic Analysis of Digital Filters

The paper introduces a simple tool for symbolic and semisymbolic analysis of digital filters using MAPLE library SYRUP. The library is originally intended for the continuous-time electrical circuit analysis, but, after simple completion can serve for digital circuit analysis as well. Mathematical program MAPLE environment simultaneously enables the post-processing of the results obtained. Some examples showing transfer function H(z) evaluation and the following sensitivity computations, design rules derivation using the modified SYRUP library illustrate the facilities of the presented tool.
