## Description

This new textbook in signals and systems provides a pedagogically rich approach to what can commonly be a mathematically dry subject. With features like historical notes, highlighted common mistakes, and applications in controls, communications, and signal processing, Chaparro helps students appreciate the usefulness of the techniques described in the book. Each chapter contains a section with MatLab applications.

## Key Features

- Pedagogically rich introduction to signals and systems using historical notes, pointing out "common mistakes", and relating concepts to realistic examples throughout to motivate learning the material
- Introduces both continuous and discrete systems early, then studies each (separately) in more depth later
- Extensive set of worked examples and homework assignments, with applications to controls, communications, and signal processing throughout
- Provides review of all the background math necessary to study the subject
- MatLab applications in every chapter

## Readership

2nd and 3rd year Electrical/Computer Engineering students in Signals and Systems.
