FILTERS WITH POLES HAVING EQUAL VERTICAL SPACING

Abstract

In the Butterworth criterion for maximally flat low-pass amplitude response, the poles are spaced by equal angles on a unit circle in the left hand s-plane. This configuration does indeed give a good cut-off in filters but at the expense of the transient response. The poor transient response is due to the poles whichAPPROACH THE J-AXIS; THEIR SPECIFIC CONTRIBUTIONS WILL BE DESCRIBED MATHEMATICALLY. The above problem was considered when a filter was needed to give a band-limited output to an input of sampling pulses. The poles were placed on the unit circle, with equal vertical spacing, so as to try to compromise between good cut-off and acceptable transient response. (Author)
