This book is a self-contained introduction to the theory of signals and systems, which lies at the basis of many areas of electrical and computer engineering. I

The aim of this book is the study of signals and deterministic systems, linear, time-invariant, finite dimensions and causal. A set of useful tools is selected

As in most areas of science and engineering, the most important and useful theories are the ones that capture the essence, and therefore the beauty, of physical

Signals and systems enjoy wide application in industry and daily life, and understanding basic concepts of the subject area is of importance to undergraduates m

Exploring signals and systems, this work develops continuous-time and discrete-time concepts, highlighting the differences and similarities. Two chapters deal w
