Multirate filtering techniques are widely used in both sampling rate conversion systems and in constructing filters with equal input and output rates in the case where the use of a conventional method becomes extremely costly. The purpose of this paper is twofold. First, this paper gives a short review on designing proper digital filters that are useful in… (More)

Complementary infinite-impulse response (IIR) filter pairs can be synthesized to generate power-complementary, allpass complementary, or magnitude-complementary filter pairs (see, e.g., [1]). A very attractive alternative to generate a power-complementary low-pass/high-pass IIR filter pair is to use lattice wave digital (LWD) filters (parallel connections… (More)

This paper introduces three classes of complementary recursive low-pass/high-pass filter pairs with an adjustable crossover frequency in such a way that the stopband attenuation of both filters remains the same. For each class, the filter pair is constructed using two allpass sub-filters as building blocks. Based on the properties elliptic minimal Q-factors… (More)

Efficient multirate filters have been developed during the past three decades for implementation of digital filters with stringent spectral constraints (Crochiere & Rabiner, 1981, 1983; Ansari & Liu, 1993; Bellanger, 1984, 1989; DeFata, Lucas & Hodgkiss, 1988; Vaidyanathan, 1990, 1993; Fliege, 1994; Zelniker & Taylor, 1994; Proakis & Manolakis, 1996; Mitra,… (More)

A new design method for multiplierless IIR halfband filters and Hilbert transformers is presented. The coefficients of the halfband filter and the Hilbert transformer are determined using the same procedure. The minimal number of shift-and-add operation design (multiplier-less) is based on the sensitivity analysis and the phase tolerance scheme.

A new straightforward design of a special class of elliptic IIR lters is presented. The major goal is the complexity reduction of the realized digital lter. The multiplier coe cients are implemented with limited number of shift-and-add operations. This method is also called "multiplierless". Unlike classical design, a closed-form relations are derived… (More)
