Wavelet theory had its origin in quantum field theory, signal analysis, and function space theory. In these areas waveletlike algorithms replace the classical Fouriertype expansion of a function. This unique new book is an excellent introduction to the basic properties of wavelets, from background math to powerful applications. The authors provide elementary methods for constructing wavelets, and illustrate several new classes of wavelets. The text begins with a description of local sine and cosine bases that have been shown to be very effective in applications. Very little mathematical background is needed to follow this material. A complete treatment of bandlimited wavelets follows. These are characterized by some elementary equations, allowing the authors to introduce many new wavelets. Next, the idea of multiresolution analysis (MRA) is developed, and the authors include simplified presentations of previous studies, particularly for compactly supported wavelets.Some of the topics treated include:oSeveral bases generated by a single function via translations and dilationsoMultiresolution analysis, compactly supported wavelets, and spline waveletsoBandlimited waveletsoUnconditionality of wavelet basesoCharacterizations of many of the principal objects in the theory of wavelets, such as lowpass filters and scaling functionsThe authors also present the basic philosophy that all orthonormal wavelets are completely characterized by two simple equations, and that most properties and constructions of wavelets can be developed using these two equations. Material related to applications is provided, and constructions of splines wavelets are presented. Mathematicians, engineers, physicists, and anyone with a mathematical background will find this to be an important text for furthering their studies on wavelets.
