This is a marvelous book. It is informative, engagingly written and readily accessible to those like myself with little scientific or technological background. I read it with considerable fascination.
J. Ronald Spencer, Associate Dean, Trinity College
The students in my telecommunications technology course found Truxal's text accessible and informative; they especially enjoyed his many good examples. I would have had great difficulty teaching the course without this book.
Charles Duke, Vice-President for Academic Affairs and Dean of the Faculty
At Syracuse University we have used John's notes for this book in a large and very successful course entitled 'The Age of Electronic Messages' for students in our non-technical disciplines. The material covered makes it possible to deliver substantial technical information to students having little or no technical background.
Bradley J. Strait, Dean of Engineering
A marvellous and sweeping survey of the vital area of communications technology. Will be as informative and useful to an electrical engineering student as to one in the liberal arts.
Jack Ruina, Professor of Electroincal Engineering, MIT
