Analog Communication has been specially designed for use by the undergraduate students as well as the faculty of electrical, electronics, and communications engineering. It provides an exhaustive coverage on the fundamental concepts and recent developments in communication theory.The book follows a bottom-up approach by buiding up the basic concepts of conventional modulation systems in the initial chapters and describing the latest trend in communications towards the end. It covers, after a brief introduction on the concepts of communication theory, chapters on Amplitudemodulation, Angle modulation, Pulse modulation and also discusses the concept of TDM, FDM, Delta and adaptive Delta modulations. The book also provides a chapter on Digital communication that contains coverage on the concept of FSK, PSK, QAM etc in a brief manner. A separate chapter on "Noise"highlights the different type of Noise encountered in Communication systems and their effect on various types of Modulation.Written in a lucid manner, the book includes a large number of circuit diagrams, worked out examples, important formulae, and graded questions for practice, thereby, enabling the users to have a sound grasp of the concepts presented in the book and their applications.
