Hi Chuck. Thanks for the rundown. This mostly makes sense to me, except this:
w(n)-fb1*w(n-1)-fb2*w(n-2)=x(n) ff1*w(n)+ff2*w(n-1)+ff3*w(n-2)=y(n) so, y(n)-fb1*y(n-1)-fb2*y(n-2)=ff1*x(n)+ff2*x(n-1)+ff3*x(n-2)
I can't seem to connect them. The dummy-variable equations seem unnecessarily dense. But, so there's nothing special about a biquad filter; just a 2nd-order IIR filter. -Chuckk _______________________________________________ [email protected] mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
