The Age of Electronic Messages

From New Liberal Arts

The Age of Electronic Messages

By John G. Truxal





What are the frontiers of today's communications technology? The Age of Electronic Messages explains the scientific principles on which this technology is based and explores its capabilities and limitations, its risks and benefits. In straightforward language accompanied by numerous illustrations, Truxal describes the communications technology that has become such an integral part of today's work and leisure. He provides accounts of the bar codes used in supermarkets and the postal system of the way signals are described in terms of frequencies and in digital form of hearing and audio systems, of radio and navigation, of medical imaging, and of television broadcasting and narrowcasting. Unlike other books on the subject, The Age of Electronic Messages takes into account the sociology of the new communications technology as well as its mathematical and physical underpinnings.

The Age of Electronic Messages is included in the Alfred P. Sloan Foundation sponsored series, the New Liberal Arts.

  • 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
