FIR design software
« on: August 19, 2011, 09:06:34 pm »

I'm looking for a free-to-cheap piece of sorfware that will generate filter coefficcents for me and export as. csv or .dat . It'd be awesome if I could quantize them to 32bit fixed and visualize their performance before loading onto my dsp.

I have alignment delay that I can burn up with this filter. 1991 taps should be enough to be dangerous.  :D

Hi,

This is pretty useful, but it might be more than you require.

Thanks Iain. That sure fits the bill. Very user friendly. The catch is for that kinda money I think I could bribe a university student to do it in MATLAB twice over for me.

Octave and SciLab both have a DSP section, but I have no idea what it's like.

Hey Hayden,
not sure which DSP your using but maybe these will help :-
http://www.cellsoft.de/windows/winfirsupport.htm  that does remez and window FIR

There's a Java based thing called FIWIZ at:- http://www.icsi.berkeley.edu/~storn/fiwiz.html (also a Windows executable as well)  :)

Cheers,
ferrit

We use LEAP5 / FilterShop. Works like a charm. http://www.linearx.com/
