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.
