Hi All, Any guys who ever used IIR filters? I got problems as below:
I want the IIR filter works as: y[n] = 1.8*x[n] + 0.8*y[n-1] Then I set the feed forward taps as [1.8], feeback taps as [0.8], just like self.iir_filter_xxx_0 = filter.iir_filter_ffd(([1.8]), ([0.8]), True) But my testing result show that the feedback taps are not involved in computing at all, thus my output turns to y[n] = 1.8*x[n] I don't know anything wrong happened to my usage... Need help. Thanks -- Alex,
