Students without extensive background in the field are offered an understanding of the principles and applications of analog and digital instrumentation in this text. Among the topics examined are basic analog and digital electronic components, systems theory and the design of analog signal conditioning circuitry for amplification, filtering and level shifting of signals originating from a variety of transducers. Also included is a detailed description of how to interface analog-to-digital converters to a personal computer, in order to digitize and display these signals, store them on magnetic media and perform elementary digital filter operations. Furthermore, the book provides a review of operational amplifiers, instrumentation amplifiers, and systems theory. Numerous examples and problems are presented throughout the text, and laboratory experiments concluding each chapter provide "hands on" experience in all areas covered.
