Title: Accurate phase measurement systems for electrical signals

Course program:
One of the most important characteristics of a sinewave signal is its phase. The phase is the time (instant) for a given signal value on a waveform cycle. Usually, the phase is an expression of relative time difference between two corresponding features (peaks or zero crossings) of two waveforms having the same frequency.
The phase is used in several application fields for indirectly measuring displacement, strain, acceleration, power quality, and for characterizing circuits and components in the frequency domain.
The aim of the course is to present a review of phase measurement systems for electrical signals. The course program consists of the following topics:
– Definition of the phase of a signal and classification of the phase measurement systems available in literature;
– A review of methods based on event counting: digital counter;
– A review of methods based on modulation: Vector Network Analyzer;
– A review of methods based on sampling;
– Description of an innovative method proposed by LESIM and NIST.
