A new method for designing two-channel causal stable IIR PR filter banks and wavelet bases is proposed. It is based on the structure previously proposed by Phoong et al. (1995). Such a filter b...

The mannose 6-phosphate/insulin-like growth factor II receptor (M6P/IGF-IIR) is a protein that facilitates the transport of acid hydrolases into the lysosome. We have shown that chronic ethanol consumption lowers the M6P/IGF-IIR content in rat hepatocytes. Here, we determined the steady-state level of mRNA encoding M6P/IGF-IIR, as well as the rate of receptor synthesis, to ascertain whether the...

The introduction of a simple correction term in gradient algorithms for adaptive IIR filtering is shown to improve their convergence and robustness. The error surface, i.e., the mean squared value of the output error as a function of adaptive coefficients, is quadratic in adaptive FIR filtering and thus a simple gradient search works well. This is not the case in adaptive IIR filtering where th...

This paper describes a design of digital hearing aids. This study shows that design of Infinite Impulse Response (IIR) digital filter with Teaching-learning-based-optimization (TLBO) gives good result in digital hearing aids. TLBO algorithm is used to optimize the filter coefficient of IIR filter. The error between desired magnitude response and actual magnitude response will be minimized by th...

The paper presents a greedy search method based on binary successive approximation-evolutionary search (BSA-ES) strategy to design stable infinite impulse response (IIR) digital filter using L1 optimality criterion. The stability constraints are well taken care of during the design procedure. The filter designed based on L1-approximation error possesses flat pass-bands and stop-bands to that of...

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...

In this paper method of design and optimization of stable IIR digital filters with non-standard amplitude characteristics using continuous ant colony optimization algorithm ACOR is presented. In proposed method (named ACO-IIRFD) dynamical changes of parameters in designed filters are introduced. Due to these dynamical changes of filter parameters, design of IIR digital filters with small deviat...

This Paper describes a simple computer-aided design approach for designing Infinite impulse response (IIR) digital filters. IIR filter is essentially a digital filter which depends not only upon the Input data but also upon one or more previous output values. A variety of techniques are available for the designing of IIR Filters. This Paper is based only upon Analog to digital mapping technique...

Filters are used to implement signal transforms, and filter design is a very important part of the signal processing field. There are currently 2 types of filters available: the finite impulse response (FIR) filter, and the infinite impulse response (IIR) filter. While FIR filters have desirable traits such as stability (an absence of poles), IIR filters are able to generate outputs more effici...
