In this paper, a new model order reduction phenomenon is introduced at the design stage of linear phase digital IIR filter. The complexity of a system can be reduced by adopting the model order reduction method in their design. In this paper a mixed method of model order reduction is proposed for linear IIR filter. The proposed method employs the advantages of factor division technique to deriv...

LANIX, Inc. introduced in March a powerful new version of its graphical filter design package available as part of the SystemView by ELANIX dynamic system simulator. This new filter design package gives designers the ability to design linear systems as Elliptic Filters and Sin t/t Filters and incorporate these filter types into their system simulation. These filters are essential for designers ...

This paper aims to establish a solution methodology for the optimal design of digital infinite impulse response (IIR) filters by integrating the features of cat swarm optimization (CSO) and differential evolution algorithm (DE). DE is a population based stochastic optimization technique which optimizes real valued functions. It requires negligible control parameter tuning but sometimes causes i...

G. Maclair, M. Ries, C. Moonen IMF CNRS / University of Bordeaux 2, Bordeaux, France Purpose/Introduction: The UNFOLD method can be used to accelerate dynamic MRI acquisitions [1] and to remove artifacts in parallel-imaging and partial-fourier imaging [2]. The essential basic reconstruction step of the UNFOLD method is a temporal low-pass filter. Recent filtering approaches can be coarsely clas...

A new class of two-channel IIR/FIR filter banks was introduced in [1] with half-band IIR analysis filters and FIR synthesis filters. This type of filter bank features very lowcomplexity analysis filters and simultaneously a low overall complexity. In this paper, we consider finite-wordlength effects of these filter banks.

Digital filters with linear phase responses, that is, constant group delay responses are needed in many applications for signal and image processing. In this paper, a novel method is proposed for designing maximally flat IIR filters with flat group delay responses in the passband. First, a system of linear equations are derived from the flatness conditions of IIR filters given in the passband a...

In signal processing it is often required to have multiple-notch filters which simultaneously possess a very selective magnitude response and a transient response of short duration. Multiple-notch filters are usually used to remove the powerline hum and its harmonics. It is known, that sharper notches are obtained by either using more coefficients in FIR filters, or by placing the pole closer t...

This paper proposes a novel method for designing two-channel and M-channel causal stable IIR PR filter banks using cosine modulation. In particular, we show that the PR condition of the two-channel IIR filter banks is very similar to the two-channel FIR case. Using this formulation, it is relatively simple to satisfy the PR condition and to ensure that the filters are causal stable. Using a sim...
