This book introduces Radio Frequency Modulation to a broad audience.  The author blends theory and practice to bring readers up-to-date in key concepts, underlying principles and practical applications of wireless communications.  The presentation is designed to be easily accessible, minimizing mathematics and maximizing visuals.

Arvustused

The book is easy to understand, with a smooth flow of presentation and a focus on key technical factors. It also provides specific and useful examples at the end of each section. ... the book is a concise, brief, informative, and excellent tutorial for introducing readers to wireless signal modulation. This book is an exemplar in its domain. It is very useful as a complementary source/reference for undergraduate students in the area of wireless data communication.
