Abstract
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.
