DIGITAL MEASUREMENT OF PHASE DIFFERENCE - A COMPARATIVE STUDY OF DSP ALGORITHMS
Journal Title: Metrology and Measurement Systems - Year 2005, Vol 12, Issue 4
Abstract
The paper compares nine methods of measurement of the phase difference of digitized sinusoidal signals mainly according to their sensitivity to sampling non-integer number of signal periods. The investigated methods can be classified into four groups - modifications of classical zero-crossing based measurements, virtual vector voltmeter, DFT-based measurements, and modifications of sine-wave fit algorithm. Results of both simulations and measurements are presented.
