Electrical Measurement Techniques

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.

Highlights the electrical engineering aspects required for a physics laboratory Covers sensor technology, amplifiers and filters, instruments and probes, transmission cables and noise shielding Is intended for students working in a physics/chemistry laboratory to learn electrical engineering
