It begins with the study of specific communication systems and gradually develops the underlying role of the signal-to-noise ratio and the bandwidth in limiting the rate of information transmission. The student is also introduced to the concept of the power density spectrum of non-random signals. This concept is then extended to random signals without any formal development. 

Features 

• Throughout the book, the emphasis is on a physical appreciation of the concepts rather than mathematical manipulation. 

• Wherever possible, the concepts and results are interpreted intuitively. 

• The basic concepts of information theory are not introduced as axioms but are developed heuristically.  aContents:
