WebAttributes of the different IIR filter methods: Butterworth – Flat response in both the pass and stop band, but has a wide transition zone. First described by British physicist Stephen Butterworth in 1930. Inverse Chebyshev – Flat in the pass band, with a narrower transition width than the Butterworth filter, but has ripple in the stop band. WebButterworth filters do not have pass-band and stop-band ripple and are commonly known as "maximally flat magnitude" filters. These filters have the flattest amplitude response of all the available filters. The following graph shows an example of a low-pass response curve. This filter type also supports high-pass, band-pass and band-reject filters. WebA sample pole-zero plot and frequency response of are shown in Figure 8.20 .
