The intent of this book is to cover the basics that I believe have been either left out of your education or forgotten over time. Hopefully it will become one of those well-worn books that you drop on the desk of the new guy when he asks you a question. There is something for every student, engineer, manager, and teacher in electrical engineering. My mantra is, "It ain't all that hard " I believe that way more than 50% of the people who read this book will get something out of it, so good luck, read on: It ain't all that hard Well, that about says it all. If you do decide to give this book a chance, I want to say thank you, and I hope it brings you success in all you do
