Iterative least squares algorithms for digital filter design.
… algorithms to simplify and improve the design of IIR digital filters and M-band cosine modulated filter banks. These algorithms are based on the Iterative Least Squares (ILS) approach. We first review the various Iterative Reweighted Least Squares (IRLS) methods used to design Chebyshev and …

A new technique to reduce phase distortion of recursive filters for video and image processing
IIR filters require less multiplication and less memory to perform filtering than their FIR counterparts. On the other hand, IIR filters have nonlinear phase response as a side effect. This is a major concern in applications such as video and image processing. In this thesis, a new method of …

Recursive backpropagation algorithm applied to a globally recurrent neural network
… in the same way infinite impulse response (IIR) filters can replace longer finite impulse response (FIR) filters. This thesis presents a new adaptive algorithm that trains recursive neural networks. This algorithm is based on least mean square (LMS) algorithms designed for other adaptive …

Study of circularly symmetrical two-dimensional digital filters possessing separable denominator transfer functions
… presence of circular symmetry in such designed filters by parameter modifications. In keeping with the simple design criteria, the two-dimensional filters studied in this thesis have been designed starting from two one-dimensional filters as an independent product. Only IIR Filters have been …

Low power, reduced complexity filtering and improved tracking accuracy for GNSS
… the Analog to Digital Converter (ADC)by the filters associated with the decimation process. The power dissipation and the hardware complexity of the decimator can be reduced substantially by using a minimum-phase Infinite Impulse Response (IIR) filter. For Global Positioning System (GPS) …

Iterative design of l(p) digital filters
The design of digital filters is a fundamental process in the context of digital signal processing. Being essential building blocks, digital filters are used in diverse areas ranging from medical imaging or audio and video processing, to highly sophisticated military applications (among many …

Design of digital differentiators
… are designed as both infinite-impulse-response (IIR) filters and finite-impulse-response (FIR) filters. The proposed differentiators have low-pass magnitude response characteristics, thereby rejecting noise frequencies higher than the cut-off frequency. Both steady-state frequency-domain …

Adaptive Control using IIR Lattice Filters
This work is a study of a hybrid adaptive controller that blends fixed feedback control and adaptive feedback control techniques. This type of adaptive controller removes the requirement that information about the disturbance is known apriori. Additionally, the control structure is implemented in …

Novel Methods for Recording and Analysing High-Density EMG Signals of the Hand & Forearm
… response (FIR) and infinite impulse response (IIR) filters; data analysis with signal segmentation, feature extraction, data reduction and interpolation techniques. For visualisation, the distribution of myoelectric activity was imaged by transforming HD-EMG data into 2D spatiotemporal maps. …
