Impact of sampling frequency on accuracy of unbalance factor measurement by DFT

The proposed paper is to discuss the problem of accuracy of unbalance factor measurement by discrete Fourier transform (DFT). Particularly, a problem of inappropriate sampling frequency is considered, when signals are sampled non-coherently. The measurement window width and its shape are considered as well. All analyses are based on analytical solutions as well as simulation and experimental research.
