Instrumentation (the choice and use of sensors and the processing of signals from them) is a subject of importance to engineering, science, and medicine. From the student undertaking a laboratory investigation to the operators of a nuclear power plant or medical equipment, accurate measurements are an essential pre-requisite to the understanding and control of all physical processes. This is a concise text covering data acquisition and analysis in an integrated fashion. This book is intended for instrumentation course in EE Department or as part of mechanical, aerospace, automotive, etc. engineering degree.

The book was developed from material prepared for a course in instrumentation for final year mechanical engineering undergraduates. The approach used is to present instrumentation from the viewpoints of both electronics and signal analysis. The sensors and electronic circuits likely to be needed by a final year student project and for postgraduate research, are comprehensively covered. It forms a suitable degree-level text for students of engineering, science or medicine seeking a practical guide to instrumentation. It is also hoped that the book will be of use to practising engineers in general. The authors' aim throughout has been to write a book which guides the reader through the intricacies of specifying and selecting an instrumentation system, acquiring data without corrupting or distorting it in the process, and applying sensible signal analysis techniques. Examples and case studies are used to illustrate the techniques discussed, including many drawn from real-life instrumentation problems encountered by the authors in engineering, physics and medicine. The sequence of chapters follows the flow of data from the primary sensing element, through transduction, signal processing and digital conversion to digital signal analysis techniques. This logical sequence ensures that the design process is undertaken in the correct order, and provides continuity for the reader.
