Electrical Measurement Techniques (eBook)

This book highlights the electrical engineering aspects of a typical physics laboratory. To perform a sound experiment in a physics laboratory, it is paramount that readers understand the equipment and methods used to collect the data. This includes sensors (e.g., thermocouples and vacuum gauges), amplifiers (e.g., instrumentation amplifiers and lock-in amplifiers), oscilloscopes and probes (active probes and current probes), transmission cables (50-ohm termination) and noise shielding (grounding), spectrum analyzers (FFT and heterodyne technique), ADCs and digital signal processing, convolution and correlation, data analysis such as curve fitting, and uncertainty calculations (uncertainty 'budgets'). The readers need to know about electromagnetic crosstalk, time-to-digital converters, student-t distributions, PID controllers, spectral leakage, and windows. This book helps readers understand all of that.

Dr. Lars Bengtsson is an associate professor in Physics at the University of Gothenburg and has specialized in electrical measurement system and embedded measurement system. He is teaching embedded systems and electrical engineering at both University of Gothenburg and Chalmers University of Technology. He has published several scientific papers on electrical measurement techniques and on pedagogical aspects on teaching in higher education in the STEM subjects. His research is mainly focused on customizing electrical measurement systems for physics laboratories (atomic and nuclear instrumentation).
