Hi list,
I am trying to implement an IIR filter which has the following equation :
Y[k] + a[1]Y[k-1] + a[2]Y[k-2] = X[k]
where X[k] is here a dirac to obtain the impulse response of the filter (of course, first two calculations are set with null samples) I get stuck as I try to get the feedback loop of the filter and Pd send me an "DSP loop detected" error message
the only way I know to avoid DSP-loop is using s~/r~ with block~, or using a delay line (but this is not your case since you are building filters)
