Description

This Mathematica notebook provides many functions that are useful when designing Infinite Impulse Response (IIR) filters. This notebook is limited to Butterworth and Chebychev polynomial approximations, and transformations of these polynomials into lowpass, highpass, bandpass, and band reject filters. This report also describes how these continuous-domain filters can be implemented as digital filters.
