This book provides a clear and detailed introduction to the use of wavelets for signal processing, based on the 'lifting' approach introduced by Sweldens in 1994, and later by Sweldens and Daubechies in 1996. I found Chapter 7 on lifting and filters particularly interesting and elegant, especially with regard to the use of the z-transform to represent such operations as signal shifting to the left (corresponding to multiplication by z--p.63, Eq.7.10) and shifting to the right (corresponding to division by z--p.64, Eq.7.11). Down sampling and up sampling were also addressed in a mathematically attractive manner. These mathematical elements were also well-represented by diagrams that showed such things as how a signal is split into even and odd components (p.65, Fig.7.1), or how the even and odd components are reconstructed (p.66, Fig.7.2). As the authors admit, however, there are 'deeper mathematical results that we cannot cover in this book'--questions that require a 'substantial background in Fourier analysis and functional analysis' (p.78). For those interested in such questions the authors direct the reader to Daubechies' and Cohen and Ryan's. In addition, a more general and simpler introduction to wavelets that is accessible to advanced undergraduates (including the use of wavelets in signal processing) is provided by Burrus et al..

There is a vast mathematics literature on wavelets. Much of this literature deals with wavelets from a theoretical point of view. Although books like Strang and Nguyen's 'Wavelets and Filter Banks' are well written math books, their emphasis is on mathematics, not application.
For example, not until Chapter 8, half way through the book, do Strang and Nguyen discuss the mathematics for dealing with a finite, rather than an infinite data set. 'Ripples in Mathematics' is the seventh book on wavelets that I've worked with. Best Y Taylor Bases Fisiologicas De La Practica Medica Pdf Editor. So far it is the best. The concentration is on applying wavelet techniques.
Samsung Cell Phone Driver Download Free. The book approaches wavelets through a relatively new technique developed by Wim Sweldens and others called 'the Lifting Scheme'. The lifting scheme provides a structure for wavelets that is easier to understand.
Lifting scheme wavelets also have the elegant feature that the transform and the inverse transform are mirrors of each other. The authors of 'Ripples in Mathematics' keep the mathematics level at a relatively introductory level (e.g., relative to some of the other wavelet books). 'Ripples in Mathematics' provides the first explaination of wavelet packets that I have understood. Even better they discuss the actual implementation of the wavelet packet algorithm. They also provide a chapter that covers wavelets applied to finite data sets in a clear non-theoretical fashion (I found this much more approachable than Strang and Nguyen). The perfect wavelet book for me has not yet been written, so I have given this book only four stars.
