A book which deals with the practical aspects of both analogue and digital electronic measuring systems. The author discusses these systems with the designer in mind, giving information which will help readers to use electronic measuring tools in the most effective way. Emphasis is placed on practical aspects of the use of electronic devices in measuring systems and to this end details of nearly one hundred applications are given including some specialized measurement and control systems. It has been assumed that readers will have a basic understanding of both electronics and measuring systems, so that theoretical and mathematical detail can be kept to a minimum. In translating his book from the original French, the author has modified and updated much of the material so that this will be an invaluable support to all those involved in the design of electronic measuring systems, or of larger complexes which include such systems. The book will also be of interest to people who are looking for an introduction to the use of electronics in measuring systems.
