 | Hi,
I'm currently looking for a PC software library that can be used to
dynamically design IIR filters such as Butterworth, Chebychev,
Elliptic ...
I can't find something that is very well kown. I'm astonished that
there is no (or very few) popular libraries to face such a common
problem. Does somebody know such a library ?
The libray I'm looking for should :
- provide routines able to provide IIR filters coefficients from high
level specifications (filter type, order, transition bands, bandpass
and bandstop ripple ...)
- be well known and/or supported by a reliable company/group
- be used, tested and validated by numerous users
- have an interface for Delphi, but I can also deal with C or C++
- be shipped with a extensive set of test routines
- be as cheap as possible, but this is not the main point
Thank you for your inputs

ON Linux you could try
http://www.watri.org.au/~ajh/libfilth/
It may not be pssible to get it to compile on windows.

| Thanks for the link Erik. The manual is a good overview of a lot of filter
design techniques.
Cheers, Syms.
p.s. Going down your post, it's spelt 'Cunnilingus'! ;-)

I have used a program from Momentum Data Systems for many years called
QEDesign. It is very good at creating filter coefficient files. It might
work for your application.

| ONEoverT is a good package. I seem to recall that Tyder were selling a
DSP library at one time.
