Abstract
In this paper, simple algorithms for fast estimation of the amplitude ratio and the phase difference of the sinusoidal signals from two channels with the same frequency are presented. Parameters are calculated from the DFT coefficients around the component peaks. The idea of the systematic error reduction with the weighted amplitude and phase DFT coefficients is used in the comparative measurement procedure.
