内容説明
Understanding Information Transmission introduces you to the entire field of information technology. In this consumer handbook and introductory student resource, seven chapters span the gamut of the field-the nature, storage, transmission, networking, and protection of information. In addition to the science and technology, this book brings the subject alive by presenting the amazing history of information technology, profiling incredible inventions and fascinating inventors, and their dramatic impact on society. Features include problem sets, key points, suggested reading, review appendices, and a full chapter on mathematical methods. Private and public funding of information technology continues to grow at staggering rates. Learn what's behind this race to be the biggest, brightest, and fastest in the field with Understanding Information Transmission.

内容説明
This introduction to digital data transmission, modulation, and error-correction coding, together with the underlying communication and information theory is an all-inclusive text suitable for all those connected with Mechanical Engineering or Computer Science. Equal emphasis is given to underlying mathematical theory and engineering practice. Not meant to be an encyclopedic treatise, the book offers strong, accessible pedagogy. This Second Edition presents enhanced explanations of key ideas as well as additional examples and problems. It also provides greatly expanded coverage of wireless communication, which has seen exponential growth since the release of the first edition.
A pedagogocal approach aimed at the 5th year EE student
A balance of theory with engineering and design
Integration of important topics such as synchronization, radio channels, and wireless communication, which are left out of competing books, or lost in more lengthy formats.
