Chebyshev low pass filter?

Question

I am looking for a chebyshev digital / analog low-pass filter for a windows forms project, preferably in C #, C ++ or c. Pseudocode will also be useful.

Answer 1

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

as well as the design of an analog filter:

Answer 3

Here is an effective C # chebyshev filter code example using NMath fft. Creating filter coefficients is not complicated and can be easily done online or with the help of a directory.
