Résumé

Fourier transforms are used everyday for solving single functions and combinations of functions found in radar and signal processing. Still, many problems that could have been solved by using Fourier transforms have gone unsolved because they require integration that is too computationally difficult. Now you can solve those integration-intensive problems with the new approach to carrying out Fourier transforms presented in this book.

By building upon Woodward's well known "Rules and Pairs" method and related concepts and procedures, this book establishes a unified system that makes implicit the integration required for performing Fourier transforms on a wide variety of functions. It details how complex functions can be broken down to their constituent parts for analysis. You can now concentrate on functional relationships instead of getting bogged down in the details of integration. This new approach to applying Fourier transforms is illustrated with many specific examples from digital signal processing as well as radar and antenna operation.
