Signals and Systems

This book is about the study of engineering signals and systems, from a discipline-neutral approach. It is a fundamental starting point in the field of engineering, and serves as the basic material that other advanced books in the engineering subject area are based. This book looks at the concepts of systems, serving as an introduction to systems theory. Also, this book examines signals, and the way that signals interact with physical systems.

While this book strives to be discipline-neutral, it currently is focused strongly on electrical engineering concepts. It is hoped that this book will be expanded to include information from other disciplines as well.
