IIR Filter Funktion with DSP5416 |
|
|
Hello, thank you for the answer,
for the function iir32(DATA *x, LDATA *h, DATA *r ...)
should be the length of 'h' 5*nbiq.
If I think right, so if the length of Filter is 8, the should be the
length of 'h' 4*5=20
If I produce the coef. with Matlab, so I get the number of coefs 24. I
can't devide this number with 5.
What should I do?
Or It isn't the coefs. what I get with matlab. "Dig Proc Toolbox"?
best regard.

I think is answered in the next reply ... that they are giving you the
coefficients for a0, a1, a2, b0, b1, and b2 ( i.e. 6 * 4 = 24 )... and
you need to divide through by the coefficient on y[n] to get only the
5 coefficients required by TI.
