I don't know if it is possible to make the math behind elliptic filters simpler. They really stand out by using somewhat exotic functions. As for the online resource about filter basics unfortunately I can't recommend any. Also IMHO the resource choice may be strongly affected by your goals.

Thanks, Vadim. I don't have a math background so it might take me longer than I wished to obtain the coefficients that way, but it's probably time to learn it. With that regard, would you have a particularly good online resource that you'd suggest for pole-zero analysis and filter design? Thanks

Hi Dario, There is a chapter on elliptical filters in Digital Filter Designers Handbook (2nd Edition) by C. Britton Rorabaugh. 16 pages all up. It includes some C++ code too. Regards, Shannon On 1/02/2018 10:00 PM, Dario Sanfilippo wrote: Hello, everybody. I was wondering if you could pl

Hmm, the Wikipedia article on elliptic filters has a formula to calculate the poles and further references the Wikipedia article on elliptic rational functions which effectively contains the formula for the zeros. Obtaining the coefficients from poles and zeros should be straightforward. Rega

Hello, everybody. I was wondering if you could please help me with elliptic filters. I had a look online and I couldn't find the equations to calculate the coefficients. Has any of you worked on that? Thanks, Dario ___ dupswapdrop: music-dsp mailing li
