A WISE method for designing IIR filters
The problem of designing optimal digital IIR filters with frequency responses approximating arbitrarily chosen complex functions is considered. The real-valued coefficients of the filter’s transfer function are obtained by numerical minimization of carefully formulated cost, which is referred here to as the weighted integral of the squared error (WISE) criterion. The WISE criterion linearly com...
متن کاملDesigning IIR Digital All-Pass Filters by Successive Projections Method
The transfer function of IIR all-pass filters is a rational function of ω. However, the optimization of such a rational function using the successive projections method, which has a wider range of application than the Remez algorithm, has not been presented. In this paper, we propose designing IIR allpass filters using the successive projections method. key words: successive projections method,...
متن کاملA Novel Methodology for Designing Linear Phase IIR Filters
This paper presents a novel technique for designing an Infinite Impulse Response (IIR) Filter with Linear Phase Response. The design of IIR filter is always a challenging task due to the reason that a Linear Phase Response is not realizable in this kind. The conventional techniques involve large number of samples and higher order filter for better approximation resulting in complex hardware for...

A novel method of the IIR filter design using the genetic algorithm is described in the paper. Newly, a simplex direct search method is included to the algorithm to enable its faster convergence. The design procedure is implemented in the MATLAB program environment. The genetic algorithm applied is able to find a solution of the task successfully. Filter coefficients quantization process is inc...
متن کاملTitle A semi-definite programming (SDP) method for designing IIR sharp cut-off digital filters using frequency-response masking
This paper studies the design of frequency response masking (FRM) filters with infinite duration impulse response (IIR) model and masking sub-filters. They are useful in realizing sharp cutoff digital filters with low passband delays. The designs of the model and masking filters are carried out by means of semidefinite programming (SDP) and model order reduction. Design results show that low co...
