Specific Remez algorithm source

Started by flor...@laposte.net May 10, 2004
Hi Everybody

I'm looking for the 'C' source of a Remez algorithm which is altered
to design arbitrarily long filters with arbitrarily many linear bands.

In fact, the MatLab function 'remez' do this but I need a 'C' source
because I work under Labwindows CVI and the equivalent function in
Labwindows CVI doesn't carry out this specification...

If anyone know where I can find a C source which do this
specification, or if anyone can help, please let me know

cheers

Florent
I presume you mean Parks-McClellan based on Remez...

Search on Jacob Janovetz for C code.....

Not sure if it'll do what you want, but Jake Janovetz wrote a C version some time ago: http://www.janovetz.com/jake/ See the "McClellan-Parks Program" section. Ciao, Peter K. -- Peter J.
