Information technology is arguably the most important scientific topic needed for understanding and participating in our increasingly complex technological world. Using simple physical arguments and extensive examples, Information and Measurement, Second Edition shows how this theory can be put into practice. Twice awarded the UK National Metrology Prize by the National Physical Laboratory for his outstanding contributions to measurement science and technology, the author includes the basic mathematical, physical, and engineering concepts required, illustrating their interrelationship in a clear, concise manner. The broad coverage includes topics taught in a variety of courses.
This book will be an invaluable study aid for senior undergraduate and graduate students in physics, electrical engineering, and computer science, specifically studying instrumentation, measurement science, and information science. It will also be a useful reference for practicing scientists and engineers.
