IR filter

Dec 10, 2012 at 12:25 PM

Hi,

will there be support for IR filter in Math.NET Numerics?

I know there is Math.NET Neodym, but it depends on the discontinued Math.NET Iridium. It would be great to have the filters on top of Math.NET Numerics.

Yes, it would make sense to port them over (also all the windowing functions); we already have ported some sample generators to the .Signals namespace.

What specific filters would you need? Also filter coefficient designers/calculators or are they already pre-computed in your case?

Thanks,
Christoph

PS: funny how people continue to cross-post to Meta Numerics ;) (no problem, just observed it more often recently)

We are interested in IIR filters for which we have pre-computed coefficients (no need for coefficient calculators ala butter()). The zero-phase filter filtfilt() would be really helpful, too.

Thanks,
Thomas
