An analog filter design software package using Mathematica

In this paper, a software package used to design analog filters is described. This filter design tool uses Mathematica from Wolfram Research as the numerical engine. This is called MathFilters. With this package, students or practising engineers should be able to perform an analog filter design in a few seconds, giving more attention to what can be done with the filter instead of getting lost in endless cumbersome numerical calculations. Several examples, showing how MathFilters works, are included. This package runs on an IBM-compatible PC under Windows 95 with Mathematica 3.0.
