"This tutorial is intended to help non-engineers who want to learn something about the technicalities of radio and television. It should also be useful for engineers in training, or those in technical occupations who want an overview of areas outside their area of expertise. We explain the jargon of broadcasting and describe the underlying principles, standards, and equipment for broadcast facilities, in terms a layperson can understand. The third edition has been completely revised to reflect the increasing use of digital techniques in all aspects of television and radio broadcasting. It has been reorganized and some obsolete material removed, while also updating the basic information on traditional analog technologies. New chapters have been added to provide an overview of first principles and current standards in the broadcast industry. We concentrate on over-the-air broadcasting from U.S. radio and television stations, but also mention some of the other methods of program delivery to the home and outline some of the different standards and technologies used in other countries."
