Thanks.
That's quite a lot of stuff in there and to be honest I'm not sure how
to use the library by looking at the documentation (which just contains
the PLL papers) and/or code.
Again here most code works on 'array = filter (array)' and not 'sample =
filter(sample)' (see for example

Sorry, here we are https://sourceforge.net/projects/dsp4j/.
there are subprojects fms(https://de.wikipedia.org/wiki/Funkmeldesystem

Thanks!
The one technical question I have is whether it is okay
P.S.: Just tested it with 3.0.0. There the Laguerre Root function is not
yet implemented. For 3.0.0 we needed to exclude the Bessel filter. That
works from 3.1.0.

Do you mean the OCTAVE/MATLAB "filter" command? If you limit that to FIR
coefficients then that's equivalent literally to a convolution operation
which we already have. (that FIR filtering is the convolution function I
have to de-bunk every year in my DSP class because in

Yes of course I would provide support and of course see it through to
the release. That comes without saying.

Hi both,
great to get such a positive response.

Dear Bernd,
Thank you for this interesting contribution. I use these sorts of filters
frequently so I will be interested to give it a look. I just build my
Butterworths in k space so I will be interested to see how yours work
differently.

Dear all,
I've created an IIR filter library:
https://github.com/berndporr/iirj
It's a re-coded version of my / Vinnie's DSP library originally written
in C++. I've spent quite some time to make it work with the apache
Complex type and I've also used the polynomial solver for the
Butterworth
