Fourier and Laplace Transforms

This textbook presents in a unified manner the fundamentals of both continuous and discrete versions of the Fourier and Laplace transforms. These transforms play an important role in the analysis of all kinds of physical phenomena. As a link between the various applications of these transforms the authors use the theory of signals and systems as well as the theory of ordinary and partial differential equations. The book is divided into four major parts: periodic functions and Fourier series non-periodic functions and the Fourier integral switched-on signals and the Laplace transform and finally the discrete versions of these transforms in particular the Discrete Fourier Transform together with its fast implementation and the z-transform. This textbook is designed for self-study. It includes many worked examples together with more than 120 exercises and will be of great value to undergraduates and graduate students in applied mathematics electrical engineering physics and computer science.
