Structure and Interpretation of Signals and Systems

This book is an extended version of the tutorial course given by the authors at UC Berkeley. It is a very well designed introduction into the most significant areas of the topic as seen by modern researchers and engineers. The book provides a broad view of the subject and allows to feel the flavor of applications. It gives an overview of typical engineering problems involving signals and systems and indicates essential mathematical techniques for modeling them. Using these tools the authors present a coherent theory as a basis for engineering design.The book is written in clear language thus making the subject, which is not simple, easy to understand. It is perfectly suitable for an inquisitive freshman who is willing to master the material by going through numerous examples and exercises. There is also a website, which provides access to additional tutorials, labs, interactive examples and useful links.The scope of the book is such that there is hardly anything to add or delete, although, I believe it would certainly benefit from adding "further reading" sections at the end of each chapter.Although, I am not a freshman but an engineer, I love this book, because it helped me to feel the joy of dealing with signals and systems and gave me a broader vision of the subject.
