INTERPOLATION IN THE FREQUENCY DOMAIN TO IMPROVE PHASE MEASUREMENT

Dusan Agrez
Abstract:
Possibilities of an error reduction of the phase estimation with an interpolated discrete Fourier transform (DFT) for the rectangular window are described. Properties of interpolations are studied with respect to their ability for correction systematic effects of the used window. The correction is improved with considering the leakage effect of the component spectrum. Uncertainties of the phase estimations have been studied. The simulation and experimental results are presented showing the effectiveness in estimating the phase of the signal component.
