WebJun 9, 2024 · As discussed in the post on ideal filter types, the Butterworth filter is a filter approximation technique that is also known as the maximally flat filter technique. This filter gives a very flat frequency response in the Pass Band, which ensures that there are no ripples present. WebIt is well known that the traditional IIR ﬁlter design is based on the corresponding analog ﬁlter design [1]. Recently, dif-ferent direct methods have been proposed for designing IIR ﬁlters, such as [2–8]. In this paper we propose a method for a direct IIR ﬁlter design based on complex allpass ﬁlters.
