TABLE OF CONTENTS The first edition of this book was published in 1982. After 15 years, I did not realize the time it would take to do a revision. The revision process was very much like altering a dress. The effort in cutting and patching an old dress can become very time-consuming. I deleted some out-of-date material and added a great deal of new material, since the content and structure of the first edition was good. Fortunately, I had an excellent staff to assist me with the revision. I would like to extend my thanks to Mrs. Carla Scherbert, Ms. Atyeh Sohrabzadeh, Mr. Walter Strohmayer, and Ms. Maribeth Eisenmann.

I am pleased with this revised edition, and I think it will serve my readers better than an entirely new volume.
The author is deeply indebted to a number of individuals who helped make this book possible.
During the period when the book was being written, inspiration and encouragement were received constantly from Dr. F. H. Blecher and Dr. C. C. Culter of Bell Laboratories. A special thanks to Dr. Blecher who advised me to write this book based on my lecture notes.
Appreciation is owed to Mr. G. E. Huffman, Dr. M. R. Sambur, and Mr. P. Torrione of the ITT Defense Communications Division for their full support on this project, to Mr. R. A. Coleman for his...
