WebIn this video, an example of design of band pass filter for the maximally flat/butterworth response is given. The frequency response of the Butterworth filter is maximally flat (i.e. has no ripples) in the passband and rolls off towards zero in the stopband. When viewed on a logarithmic Bode plot, the response slopes off linearly towards negative infinity. A first-order filter's response rolls off at −6 dB per octave (−20 dB … See more The Butterworth filter is a type of signal processing filter designed to have a frequency response that is as flat as possible in the passband.

WebButterworth filters are desirable for their ease of implementation, good phase response, and their smooth monotonic frequency response in both the pass-band and the stop-band. However they don’t achieve the steep roll-off of Chebyshev filters, but Chebyshev filters achieve this steeper roll-off by allowing either some ripple in the pass-band ... WebAttributes of the different IIR filter methods: Butterworth – Flat response in both the pass and stop band, but has a wide transition zone.
