Description
Fourier transform theory is of central importance in a vast range of applications in physical science; engineering; and applied mathematics.
This new edition of a successful student text provides a concise introduction to the theory and practice of Fourier transforms; using qualitative arguments wherever possible and avoiding unnecessary mathematics.
After a brief description of the basic ideas and theorems; the power of the technique is then illustrated by referring to particular applications in optics; spectroscopy; electronics and telecommunications. The rarely discussed but important field of multi-dimensional Fourier theory is covered; including a description of computer-aided tomography (CAT-scanning).
The final chapter discusses digital methods; with particular attention to the fast Fourier transform. Throughout; discussion of these applications is reinforced by the inclusion of worked examples. The book assumes no previous knowledge of the subject; and will be invaluable to students of physics; electrical and electronic engineering; and computer science.
