In this paper band pass (BP) and band stop (BS) infinite impulse response (IIR) filter is designed using particle swarm optimization (PSO) algorithm.The magnitude response of the IIR filter is approximated using L1-approximation error criterion. The PSO algorithm is aoptimization technique inspired by genetics and natural evolution.The method enhances the search capability and provides a fast c...

In this paper an Enhanced Teaching-Learning Based Optimization (ETLBO) algorithm is employed to design stable digital infinite impulse response (IIR) filter using Lp-norm error criterion. The original TLBO algorithm has been remodeled by merging the concept of opposition-based learning and migration for selection of good candidates and to maintain the diversity, respectively. The multiobjective...

A new method for designing IIR digital filters with linear phase in the passband is proposed. This method is based on frequency weighted least-square error optimization using the BFGS method [15]. The gradient of the cost function with respect to the design parameters, required for the implementation of the BFGS method, is derived. The proposed method is started by obtaining an initial IIR filt...

The problem of mapping data flow graphs (DFGs) of infinite impulse responce (IIR) filtering algorithms into application specific structure is considered. Methods of optimization of DFGs are considered for the purpose of finding IIR filter structures with the high throughput and hardware utilization. Optimization method is proposed which takes into account structural properties of FPGA, minimize...

In this paper, Bireciprocal Lattice Wave Digital Filters (BLWDFs) are utilized in an approximate linear phase design of 9 th order IIR wavelet filter banks (FBs). Each of the two branches in the structure of the BLWDF realizes an Allpass filter. The low-coefficient sensitivity, excellent dynamic range and good stability properties of such filters allow their realization with short coefficient w...

Digital Video is a stream of still images called frames, which are moved such that it gives an illusion of dynamics of the objects present in the image. Video image processing is basically processing of frames and updating frames with a minimum frame rate of 16 per second to give an illusion of motion picture. The objective of the research is all about the development of high throughput image p...

Abstract— A real coded genetic algorithm is applied for designing infinite impulse response (IIR) filter based on L1approximation error criterion. The proposed real coded genetic algorithm, which is a technique for optimization inspired by genetics and natural evolution method, enhances the search capability and provides a fast convergence for calculating the optimal filter coefficients. The fi...

The linear-phase IIR filters are described in many cases, mainly due to distortion-free transmission of signals. One of the major problems of IIR filter design is stability, which can be obtained with suitable value of group delay τ . This paper concerns calculation of filter order N and group delay τ in case of quasi-equiripple design of IIR filters. We propose a novel procedure for determinin...
