21061 ez-kit bandpass demo coefficients ???

Started by Bergen June 18, 2007
Hello again.

For few weeks I'm trying to create my own FIR coefficients for 21061 
Ez-Kit Lite bandpass demo, using Matlab ( fir1, remez, sptool), without 
any results.

I written for help on many net forums. Nobody knows why my coeffs 
doesn't work.

I guess nobody even tried to made FIR for this EZ-Kite. It's using for 
its bandpass demo strange coefficients and it works:

http://wisnia.server.pl/fir/fir-2.h
http://wisnia.server.pl/fir/fir-3.h
http://wisnia.server.pl/fir/fir-4.h
http://wisnia.server.pl/fir/fir-5.h

When I'm trying to do my own, for example using this tutorial:

http://www.staff.ncl.ac.uk/charalampos.tsimenidis/EEE8091/EEE8091-HO3.html

Nothing works.

But this shitty bandpass demo is working well...

Where is hatch ? Why these bandpass coeffs are so different to mine ?
