Butterworth digital filter
WebA Butterworth filter is recursive, so it should be implemented as an IIR filter. Once you have stable filter coefficients from your Matlab testing you can simply feed them to a generic IIR algorithm (pretty simple). You can approximate the filter response with a large FIR filter and convolution, which can be moved into frequency domain to solve ... WebThe classical digital Butterworth filters (defined by L = N and M =0) are special cases of the filters discussed in this paper. Figs. 1 and 2 illustrate a classical digital Butterworth …
