Understanding Information Transmission is an introduction to the field of information engineering targeted at Information Technology students. It spans the nature, storage, transmission, networking, and protection of information. A special feature of the book is its treatment of the spectacular history of information engineering and its social effects on all of us. As information transmission has emerged as one of the hottest topics in arenas ranging from mass media to research and development, this book will be of broad general interest to anyone interested in the progress of communications technology.
