Description
Introduction to Analog and Digital Communications, second edition, offers up-to-date coverage on the principles of analog and digital communications, focusing on the fundamentals of communication theory and relating theory to practice. Adopting a “systems” perspective approach, the book focuses on the concepts of modulation theory, probability theory and signal detection, and the role of noise in communication systems. Numerous worked-out examples as well as theme examples have been included to help students develop an intuitive grasp of the theory.
