chebyshev low pass filter?

Question

I'm looking for a digital/analog chebyshev low pass filter for a windows forms project, preferably in c#, c++ or c. A pseudocode would be helpful as well.

Answer 1

Here's a web app by Tony Fisher that computes the coefficients for digital filters (common FIR and IIR types), plots the filter magnitude and phase response, and even creates an ANSI C function template:

and also analog filter design:
