Generalized Digital Butterworth Filters

One chapter of my thesis introduces a generalization of the digital Butterworth filter, that unifies the classical Butterworth filter and the maximally flat symmetric FIR filter.

The results are summarized in "Generalized Digital Butterworth Filter Design". A program for the design of these filters is part of the Matlab 5: Signal Processing Toolbox. An additional program, not available in that toolbox, is provided here.
