Ordering of poles and zeros. What is the best way to implement? ... y1=biquad(x,coefs1,states1); y2=biquad(y1,coefs1,states1); y=biquad(y2,coefs1,states1) ...
f1=dm(i4,m5); // fetch states[0], but do not inc i4. dm(i4,m6) = f8; // states[0] = x ... f1 = dm(i4,m5); // fetch states[2], but do not increment i4 ...
