Hi, There is comment in optfir.py saying "# FIXME high_passs is broken...". Can anyone send me an example to regenerate this problem? I have some spare time and I think I can help in fixing this problem (If it still exist!!!!) Regards, Firas -- View this message in context: http://www.nabble.com/Fixing-high-pass-filter-desi...

Firas, Grepping for FIXME in the code is a great way to look for ways to contribute, and thanks for offering your help. Unfortunately, that particular FIXME doesn't make clear what is broken, so perhaps you shouldn't start there. (Hmm. The FIXME has been there for almost four years. Maybe nobody uses that part of the API? Maybe it isn't broken?) -Johnathan

I haven't looked at that code in a while. I will take the assignment. Maureen Quirk and I are doing a Octave and SciPy replacement for fdatool. Maureen has spent years writing FIR and IIR design code. We are updating it to use C++ as the code was originally Fortran and written for the Cray supercomputers we used to have. This is not "make work". We need to use it in several more modern things about to be included here (such as the polyphase filter bank code I am doing from the work harris and I did this summer). We have one more teleconference meeting Friday and then code will fly out the door. The design code will follow after Maureen is happy with it. This is to be used for and will include both FIR and recursive/all pass versions of the partition filters.

Excellent. Please coordinate with me on how this gets integrated, as we're approaching "freeze" on the 3.2 release. -Johnathan
