Continuous and Discrete-Time Signals and Systems

This textbook provides a detailed study of continuous and discrete time signals and systems, at a theoretical as well as a practical level, for undergraduate as well as graduate students. The book follows a didactic approach, allowing the students to acquire a solid knowledge and skill required for the study of more advanced subjects, such as telecommunications, as well as automatic control systems. The detailed presentation of the theory in this book is accompanied by many examples, as well as hundreds of solved and unsolved exercises, that help the reader to gain immediately a deep understanding of the presented material and the way it is used in practice. Because of the mathematical complexity associated with the presented material, this book requires a good knowledge of basic concepts from linear algebra and mathematical analysis, such as, for example, elements of matrix theory, the concepts of the derivative and the integral, as well as the knowledge of the main aspects associated with differential and difference equations for the continuous and the discrete time domain, respectively. Special emphasis should also be given to well known techniques that allow the estimation of the inverse transforms, such as polynomial division, partial fractions expansion, as well as the methods of residues for the estimation of integrals of complex functions.

Digital Signal Processing with Matlab Examples, Volume 1

This is the first volume in a trilogy on modern Signal Processing. The three books provide a concise exposition of signal processing topics, and a guide to support individual practical exploration based on MATLAB programs. This book includes MATLAB codes to illustrate each of the main steps of the theory, offering a self-contained guide suitable for independent study. The code is embedded in the text, helping readers to put into practice the ideas and methods discussed. The book is divided into three parts, the first of which introduces readers to periodic and non-periodic signals. The second part is devoted to filtering, which is an important and commonly used application. The third part addresses more advanced topics, including the analysis of real-world non-stationary signals and data, e.g. structural fatigue, earthquakes, electro-encephalograms, birdsong, etc. The book’s last chapter focuses on modulation, an example of the intentional use of non-stationary signals.
