Sažetak
Sampling methods are nowadays commonly accepted for measurements of various signals and here we present our achievements in measurement of pure sine wave at low frequencies (up to about 500 Hz), that is, measure-ment of phase difference between two sinusoids. Firstly, we briefly discuss the mathematical form of samples and its implications on the calculations needed to determine the phase difference. We continue with deep explanations of an alghoritm for very accurate calculation of one parameter of the measured signals, the most important one for phase difference calculation. At the end, we present results of real laboratory measurements as the final proof of declared accuracy.
