This title presents the general principles of instrumentationprocesses. It explains the theoretical analysis of physicalphenomena used by standard sensors and transducers to transform aphysical value into an electrical signal. The pre-processing ofthese signals through electronic circuits – amplification,signal filtering and analog-to-digital conversion – is thendetailed, in order to provide useful basic information. Attention is then given to general complex systems. Topicscovered include instrumentation and measurement chains, sensormodeling, digital signal processing and diagnostic methods and theconcept of smart sensors, as well as microsystem design andapplications. Numerous industrial examples punctuate thediscussion, setting the subjects covered in the book in theirpractical context.

Ultrasonic signals are increasingly being used for predicting material behavior, both in an engineering context (detecting anomalies in a variety of structures) and a biological context (examining human bones, body parts and unborn fetuses). Featuring contributions from authors who are specialists in their subject area, this book presents new developments in ultrasonic research in both these areas, including ultrasonic NDE and other areas which go beyond traditional imaging techniques of internal defects. As such, both those in the biological and physical science communities will find this an informative and stimulating read.

This book is the first book on this technique; it describes the theory of DPSM in detail and covers its applications in ultrasonic, magnetic, electrostatic and electromagnetic problems in engineering.  For the convenience of the users, the detailed theory of DPSM and its applications in different engineering fields are published here in one book making it easy to acquire a unified knowledge on DPSM.
