Overview

An introduction to the foundations and applications for information theory. It includes the basic mathematical, physical and engineering concepts required, the author demonstrating their links and uses. The text also contains an appendix of BASIC and ""C"" program routines, topics covered are outlined in early chapters, and developed using analogies such as how CDs record and transmit sound later in the book. Each chapter includes problems on and a summary of the topics covered. Solutions to the problems are contained in a further appendix.
