Contemporary Communication Systems provides a comprehensive introduction to analog and digital communication systems. In addition to a logical and easy-to-understand presentation of fundamental principles, the book engages students in the issues relevant to system and product implementation by integrating a discussion of theoretical concepts with extensive hands-on visual and simulation resources that reinforce learning. A unique feature of the book is sufficient coverage of important topics in digital communications including compression, multiplexing and synchronization techniques. The book also explores the impact of semiconductor revolution (Moore's law) and software technologies in the realization of modern digital communication systems.
