One bit more. aInformation and Measurement provides a readable introduction to the concepts and techniques of information theory, instrumentation and measurement. Information technology is arguably the most important scientific topic needed for understanding and participating in our increasingly complex technological society. Using simple physical argument, and extensive concrete examples, such as the Compact Disc audio system, the book shows how theory can be put into practice. The coverage is broad and includes topics often taught on different courses. It includes the basic mathematical, physical and engineering concepts required, and the author demonstrates their links and uses in his customary clear style. The approach adopted, and selection of topics included, will make this an invaluable book for a wide range of readers who have previously had to forage through the literature for relevant material. 0aInformation technology. aANLcYY 003.54 L628
