This book is primarily aimed at circuit board designers. Typically these people have either no formal engineering education or a 2-year associates degree. A few have formal 4-year degrees and find themselves now designing boards either on a part time basis (as an adjunct to their normal design activities) or perhaps full-time. Almost none of them have ever received any formal education in signal integrity issues as related to board design, principally because almost no such training is offered--anywhere! Therefore, there is a need for a basic, comprehensive text that covers the causes of these problems and their solutions.
