ANALOG COMMUNICATIONThis book carries a holistic approach on the analog communication, with all the basic concepts pertaining to the subject described in it. The text provides an incisive insight into the subject via simple, elegant and explicit presentation. Organised in ten chapters, the book dexterously assimilates the various terms and techniques used in analog communication to enhance a broader understanding of the concepts and their applications. Commencing with the basic introduction, the book goes on to provide description on analog amplitude modulation, single sideband modulation, analog angle modulation, pulse modulation digital transmission of analog signals and multiplexing. Finally, it discusses about noise, random signal and processes, information theory and coding, and communication detectors and filters. The background of each topic in the book is prepared sensibly by providing suitable illustrations, numerical examples, detailed explanation of each step given, thereby making the understanding of complicated derivations easier. This well-structured book is specifically written for the undergraduate students of electronics and communication engineering, and postgraduate students of electronics. |
