PREFACE and ACKNOWLEDGEMENTS
This Student Solutions Manual for Digital and Analog Communication Systems, 8th
Edition (United States) contains complete solutions for the homework problems in the
8th Edition that are marked with a i. If the problem is designed for a MATLAB
computer solution (as denoted by a computer symbol), then a MATHCAD printed
solution is shown in this solutions manual. (MATHCAD solutions are shown since
they clearly display the algorithms used and the output takes up less space.)
MATLAB m files for these problems can be downloaded from the internet websites
maintained by the author located at

or

In the textbook, a computer symbol is used to indicate that MATLAB solutions are
provided for that material, although those homework problems marked with a
computer symbol but not including a i are available only to the instructor from
Pearson/Prentice Hall. This website is located at
/>
This solutions manual was prepared by Leon W. Couch, II, with the help and valuable
suggestions of many undergraduate and graduate electrical engineering students at the
University of Florida. Their assistance is greatly appreciated. Several graduate
students worked out solutions or contributed problems with solutions; they are:
Samel Celebi
Brady E. Gaughan
Charles S. Prewitt

Lawrence K. Thompson
Yeong-Cheng Wang
Ching-Jang Wu

Thanks also to Ronald F. Smith who wrote the original code for many of the
MATLAB M files.
The author values your comments and suggestions. Also, for future editions, new
problems and problems with computer solutions are welcomed. Please send them to:
