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 ...

http://floss.booktype.pro/csound/signal-processing-i/ 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.
