How does the Butterworth filter work? ResearchGate

WebButterworth filters are termed maximally-flat-magnitude-response filters, optimized for gain flatness in the pass band. The attenuation is –3 dB at the cutoff frequency. Above the cutoff frequency, the attenuation is –20 dB/decade/order. The transient response of a Butterworth filter to a pulse input shows moderate overshoot and ringing.

WebSep 23, 2024 · The fundamental characteristic of a low-pass Butterworth pole-zero plot is that the poles have equal angular spacing and lie along a semicircular path in the left half-plane. All points on a circle have the same distance from the center of the circle. Thus, the distance between the origin and each pole is the same, and this in turn means that ...
