This student-oriented text familiarizes undergraduates with the electronics involved in scientific instrumentation and control systems for use in research and end products. Suitable for the one- or two-semester courses, the text emphasizes electronics applications, rather than the physics or engineering of a device. This makes the material suitable for students who need a fundamental knowledge of electronics for the laboratory or workplace. Manufacturers’ data sheets for nearly every common component are gathered in a convenient appendix, making learning and applications much easier and providing students with a valuable reference tool.
