Problem with dsplib IIR function and MATLAB fdatool

Started by starbak November 10, 2003

My friend and I decided to taste a little bit of DSP programming. We are
doing a project (simple vocoder) on TMS320C5402 DSK board using Code
Composer Studio 1.22. We wanna use IIR filter function provided in the
dsplib, and MATLAB's fdatool to calculate filter coeficients. The problem is
that dsplib IIR function needs five coeficcients, but from fdatool we get
six. Anybody had same problem? Any sugestions?
