This edition of Analog Communications: Principles and Practices addresses the requirements of undergraduate engineering students of Kerala University, Mahatma Gandhi University and Calicut University. The book introduces the recent and most promising developments in the domain of analog communications. The methodology adopted relies on a simple and lucid approach to analysis without compromising mathematical rigour. The book includes several worked-out examples and chapter-end exercises. Concepts in modulation and signal processing are illustrated using MATLAB® as a simulation tool, which makes the book suitable for use in programming and simulation lab as well.In this edition, several new topics, additional solved examples and exercises, including multiple-choice questions, and a new chapter on pulse modulation systems have been included to make the contents thoroughly compliant with the present-day curriculum requirements of technical universities.
