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. We WebThe best known and most commonly used method for the design of IIR digital ﬁlters is probably the bilinear transformation of the classical analog ﬁlters (the Butterworth, Chebyshev I and II, and Elliptic ﬁlters) [9]. One advantage of this technique is the existence of formulas for these ﬁlters.
