Fast Fourier Transforms By C. Sidney Burrus
Paperback: $26.95
Ships in 3-5 business days.
This book uses an index map, a polynomial decomposition, an operator factorization, and a conversion to a filter to develop a very general and efficient description of fast algorithms to calculate...

Digital Audio Signal Processing: The Discrete Fourier Transform By Gerald Lemay
Paperback: $28.51
Ships in 3-5 business days.
The Discrete Fourier Transform (DFT) is often simply (and incorrectly) referred to as the FFT (Fast Fourier Transform). Learn the difference between the FFT algorithm, the Discrete-Time Fourier... More > Transform (DTFT), and the DFT as you explore circular convolution, enhanced spectral estimation, and other topics. Based on a teaching-learning paradigm called layering, this book reflects the authors deep teaching background. The purpose and intent of this book series is to clarify the fundamental concepts of digital audio signal processing. Software examples (MATLAB) are used throughout the text which includes analytic exercises and their solution. Gerald Lemay is currently working on his second PhD in Digital Signal Processing and welcomes comments and suggestions on this book. You may contact him through the publisher.< Less
Partial Differential Equations with Fourier Series and Boundary Value Problems By Nakhlé H. Asmar
Hardcover: $45.00
Ships in 6-8 business days.
This book provides a smooth transition from a course in elementary ordinary differential equations to more advanced topics in a first course in partial differential equations and Fourier Series. It... More > is intended for students of engineering, mathematics, and physics, with emphasis on applications. The new topics in this edition offer the instructors the option to teach a theory oriented course on partial differential equations or a course with heavier emphasis on Fourier series and boundary value problems. Beyond the core material for a basic course on partial differential equations, the book includes a number of more specialized topics that the instructor can cover or use as research projects at his or her discretion. The book contains hundreds of completely worked out examples to help students assimilate the new topics. The style is easy to follow and speaks directly to the reader. The book comes with a companion student solutions manual that the reader can download for free from the author’s website.< Less

The couple of Liouville-Boltzmann and Poisson equations governing densely populated systems By Yves R Talpaert
eBook (PDF): $2.58
Download immediately.
A method to resolve both Liouville-Boltzmann and Poisson equations is developed. A Fourier transform on the velocity space introduces the spectral equation. Next a Fourier transform with respect to... More > the radial distance leads to one and fundamental differential equation which describes the evolution of spherically symmetric systems of many bodies subject to their own gravity. The consideration of other Fourier transforms is suggested by using this original method, in the case of general systems notably. This method is a natural alternative to fluid-dynamical approach since the successive velocity distribution moments simply follow from derivation.< Less
