The Butterworth filter is an analogue filter design which produces the best output response with no ripple in the pass band or the stop band resulting in a maximally flat filter response but at the expense of a …

To illustrate some of the ideas developed in Lecture 23, we introduce in this lecture a simple and particularly useful class of filters referred to as Butter-worthfilters. Filters in this class are specified by …
