"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 ...
