Produktbeschreibung

This book features a unique, practical approach to the design of high-speed digital circuit boards. It provides designers with the tools they need to lay out digital circuit boards for fast logic and to get designs working the first time around. Presenting an alternative to the circuit theory approach, it emphasizes energy flow rather than just signal interconnection to explain logic circuit behavior. The book shows how treating design in terms of transmission lines will ensure that the logic will function, addressing both storage and movement of electrical energy on these lines.
