MFMBO filter response

One of the new filters to emerge in recent years has a magnitude response which is maximally flat beyond the origin. The filter is a generalization of the Butterworth filter. This letter presents a study of this filter including its magnitude, delay, and step responses. A filter design nomograph is also presented. These results are compared with other classical filter types. It is shown that this filter provides an attractive alternative to Butterworth, Chebyshev, Papoulis, and Halpern filters.
