Introduction

Signals and systems is one of the toughest classes you’ll take as an engineering student. But struggling to figure out this material doesn’t necessarily mean you need to sprout early-onset gray hairs and resign yourself to frown lines in your college years. And you definitely don’t want to give up on engineering over this stuff because becoming an engineer is, in my opinion, one of the best career choices you can make. See, you’re no dummy!

This book can help you make sense of the fundamental concepts of signals and systems that may be giving you some static — or even frying your brain. Even better, you can apply the tips and tricks I provide in this book to the courses you’ll take down the line — and right into the real world of computer and electrical engineering!

About This Book

Like all other For Dummies books, Signals & Systems For Dummies isn’t a tutorial. It’s a reference book that you can use as you need it. You don’t need to read each chapter cover to cover (but you may find all the material utterly mesmerizing). You can jump right to the topics or concepts that are giving you trouble, get the help you need, and be on your way with helpful insight to real-world examples of electrical concepts that may be tough to imagine in your textbook of equations.
