The uni-modal error surfaces and intrinsic stable behaviors of adaptive finite impulse response (FIR) filters make gradient based algorithms very effective in the design of these filters. Gradient based design methods are well developed for the design of adaptive FIR filters and widely applied to the distinct areas such as noise cancellation, system identification and channel equalization. Howe...

This paper introduces filter structures for interpolation and decimation by a factor of two. The structures are derived by using the frequency-response masking approach, in which the overall filter makes use of a periodic model filter, its complementary filter, and two masking filters. The periodic model filters are obtained by replacing each delay element in a model filter with M delay element...

The hardware description and implementation of adaptive infinite-impulse-response (IIR) filters for real-time applications is an important and challenging designing issue. The aim of this paper is hardware description of digital adaptive IIR filters for implementing on field programmable gate array (FPGA) chips. The direct architecture is considered for IIR filter designing and Equation-Error (...

The parallel processing systolic array architecture is designed for the real time VLSI spatio temporal 3D Infinite Impulse Response (IIR) frequency planar filter to achieve high throughput of one frame per clock cycle (OFPCC). To reduce the circuit complexity by designing the architecture, that is based on differential form transfer function of a 3D IIR frequency planar filter. The 3D Look Ahea...

This paper considers the wavelet transform generated by iterating orthonormal power-complementary IIR filter pairs with perfect reconstruction properties. For the implementation of complementary IIR filter pair, the realization structure based on two allpass subfilters in parallel connection is used. The decomposition and reconstruction properties of the example wavelet banks composed of the fi...

This paper is concerned with the design and implementation of frequencyselective recursive filters in which the filtered output is incorporated on the input side, at various lags, via a series of feedback terms. Such devices are commonly described as infinite impulse response (IIR) filters. Filters that are devoid of feedback are apt to be described as finite impulse response (FIR) filters. Rel...

In this paper, we present an alternative characteristic waveform (CW) decomposition mechanism for the Waveform Interpolation (WI) paradigm based on the Pitch Synchronous Wavelet Transform (PSWT). In this technique, IIR filters replace the conventional FIR filters of the PSWT, offering computational and spectral magnitude performance advantages, in addition to significant delay reductions. Previ...

In this paper, we present a new approach to the least-squares design of stable infinite impulse response (IIR) digital filters. The design is accomplished by using an iterative scheme in which the denominator polynomial obtained from the preceding iteration is treated as a part of the weighting function, and each iteration is carried out by solving a standard quadratic programming problem that ...

Wearable sensors are the major part of Wireless Body Area Networks (WBANs) for provision of health care services and physical activity monitoring. In this paper, a brief survey of different types of wearable sensors presented along with sensor placement. Designing of wearable sensors for ECG and Blood pressure also discussed. Comparative study of FIR and IIR noise reduction ECG filters discusse...

Considered are general, pure linear prediction schemes, where the prediction of the current sample is based on IIR-filtered past samples. Properties of these schemes are discussed, in particular, the whitening property, the realisation of the synthesis filter and its stability. The realisation problem as occurring in warped linear prediction is solved. Furthermore, it is proved that, at least f...
