Available in PDF, EPUB and Kindle. Book excerpt: This thesis is concerned with the analysis and design of FIR multirate filter banks. Focusing on the time-frequency relation of the filter bank structures, various design methods have been developed. Standard digital filtering techniques are used such as windowing, and least squares in conjunction with the multirate structures of the filter banks to obtain efficient designs that will allow a great degree of flexibility in controlling the frequency characteristics of the filters. A spectral factorisation technique is introduced to design three-channel based systems in the z-domain. This method extends the well known two-channel based design, and requires no numerical optimization. Time-domain algorithms are introduced to design M-channel systems with arbitrary length filters and arbitrary system delays. Aliasing cancellation and perfect reconstruction conditions in the time domain are addressed. A recursive technique is proposed which uses the synthesis filters from one iteration to update the analysis filters for the next. Wavelets provide a new method for time-scale analysis of non-stationary signals. Filter banks are used to construct several classes of wavelet transforms; orthonormal, bi-orthogonal, and new low delay wavelets using the time-domain formulation.

Book excerpt: Digital signal processing designs are getting larger. At the same time modern applications are demanding smaller and smaller form factors. This project is a design with a specific problem. The design is a massive Multiple-Input-Multiple-Output FIR filter array. Currently the design is supported using multiple FPGAs. The problem is getting the entire FIR filter array to fit into a single FPGA. To reduce the size of the array, this paper looked at methods of reducing the size of FIR filters. Multiple approaches were reviewed: linear-phase filters, sparse filters, multichannel filters, multirate filters and filter banks. Each approach was implemented in VHDL for simulation and synthesis results. Based on the results, each approach can be analyzed for costs and tradeoffs. Based on the analysis, two of the approaches show the most promise for massive FIR filter arrays. Those two approaches are the multichannel and the filter bank approaches. These two approaches have their limitations. However within those limitations either approach can support large FIR filter arrays within a single FPGA.

Available in PDF, EPUB and Kindle. Book excerpt: Window functions have been successfully used in various areas such as filtering, beam forming and multirate signal processing. Due to available closed form expressions, the role of windows is economical. One of the key applications is the design of FIR filters. These filters are used in decimators and interpolators which are the basic building blocks for any multirate system and filterbank. In present scenario, a system with an improved performance, better quality, little error is the prime requirement. With this objective FIR multirate filters are designed using window functions. These functions can be used to design half-band filters where fifty percent filter coefficients result with zero value. With bandpass filters more than seventy percent zero valued coefficients are obtained if they preserved the concept of half-band symmetry. On the basis of error criterion filterbanks are of two types, viz., pseudo filterbanks and perfect reconstructed filterbanks. A new linear optimization algorithm is applied to obtain the pseudo filterbanks. Lag windows can be used to design energy efficient filters called compaction filters. The compaction gain is very near to optimal ones.

Available in PDF, EPUB and Kindle. Book excerpt: Upon its initial publication, The Circuits and Filters Handbook broke new ground. It quickly became the resource for comprehensive coverage of issues and practical information that can be put to immediate use. Not content to rest on his laurels, in addition to updating the second edition, editor Wai-Kai Chen divided it into tightly-focused texts that made the information easily accessible and digestible. These texts have been revised, updated, and expanded so that they continue to provide solid coverage of standard practices and enlightened perspectives on new and emerging techniques. Passive, Active, and Digital Filters provides an introduction to the characteristics of analog filters and a review of the design process and the tasks that need to be undertaken to translate a set of filter specifications into a working prototype. Highlights include discussions of the passive cascade synthesis and the synthesis of LCM and RC one-port networks; a summary of two-port synthesis by ladder development; a comparison of the cascade approach, the multiple-loop feedback topology, and ladder simulations; an examination of four types of finite wordlength effects; and coverage of methods for designing two-dimensional finite-extent impulse response (FIR) discrete-time filters. The book includes coverage of the basic building blocks involved in low- and high-order filters, limitations and practical design considerations, and a brief discussion of low-voltage circuit design.

Abstract: Abstract of thesis entitled New Design Methods for Perfect Reconstruction Filter Banks Submitted by Tsui Kai Man for the degree of Master of Philosophy at The University of Hong Kong in August 2004 Perfect reconstruction (PR) filter banks (FBs) have found applications in signal analysis, subband coding and the construction of wavelet bases. This study considers the theory and design of two-channel structural PR FBs. One important advantage of a structural PR FB is that its design can be simplified to conventional finite-/infinite- duration impulse response (FIR/IIR) filter design problems. This study proposes a new structural FB called multi-plet FB. It generalizes structural PR FBs [Pho 1995] and triplet FBs [Ans 1999] by employing multiple lifting steps. The resulting FB is more flexible than traditional structures in choosing the system delays and the filter lengths of the analysis filters. A systematic design procedure based on second order cone programming (SOCP) is also proposed. This is particularly useful for realizing FBs with a narrow transition band. The thesis first makes a detailed study of SOCP, a powerful convex optimization method allowing linear and convex quadratic inequality constraints to be incorporated. Using this useful property, a new method for the optimal minimax and least square (LS) design of linear-phase and low-delay FIR filters with prescribed flatness and peak error is proposed. New low-delay specialized filters such as Hilbert transformers (HTs), digital differentiators (DDs), M-th band filters (MBFs), and variable digital filters (VDFs) can be designed readily by the proposed method. The proposed SOCP approach is coupled with a new constrained model reduction method, which retains the denominator of the conventional model reduction techniques and formulates the optimal design of the numerator as a SOCP, and further extended to the design of causal stable IIR filters. These novel constrained FIR/IIR design methods are then applied to the design of casual stable IIR PR triplet and multi-plet FBs. The use of a hybrid of allpass and FIR linear-phase filters also enables the bumping effect found in the conventional structural PR IIR triplet FBs to be suppressed by an appropriate choice of parameter in the triplet structure. Wavelet FBs can also be obtained by the proposed constrained filter design approach. For the multi-plet FB, a low order prototype PR FB with a much wider transition band is first designed using non-linear optimization in order to obtain a symmetric frequency response and prescribed passband/stopband ripples. A subfilter is then designed using SOCP which enables the prototype FB to be wrapped by means of frequency transformation to meet the desired transition bandwidth while preserving the PR condition, passband/stopband ripples and lifting structure. The design procedure is very robust, and can be applied to both linear- phase and low-delay multi-plet FBs. By formulating the K-regularity conditions as a set of linear equality constraints on the subfilter coefficients, multi-plet-based wavelet bases can easily be designed under the SOCP framework. The effectiveness of the proposed methods is illustrated with several design examples.
