This book is an introduction to many of the topics that an engineer needs to master in order to successfully design experiments and system measurement especially in sensor applications. In addition to descriptions of common measurement systems, the book describes computerized data acquisition systems, common statistical techniques, and guidelines for planning and documenting experiments. More comprehensive studies of available literature and consultation with product vendors are appropriate when engaging in a significant real-world experimental program. It is to be expected that the skills of the experimenter will be enhanced by more advanced courses in experimental and instrumentation systems design and practical experience.
