内容説明
Captivate your students - and entice new students to the electrical engineering major - with Roman Kuc's illuminating look at how commonplace information systems, like infra-red auto-focus cameras, compact disc systems, bar codes, credit and smart cards work, and how clever engineering solutions are used to solve technical problems. Designed for readers with no science background, the book introduces them to the thought processes used by electrical engineers to think quantitatively and then design useful systems. As a result, readers not only learn the facts behind information and transmission, coding and storage, but how these systems came to be developed in response to a shift of information to a digital medium. Unlike traditional science texts that begin with theory and then illustrate that theory with applications, this book starts with practical, real-world systems and then presents the physical theory and mathematical analysis required to understand their operation.
