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.

采样频率对DFT测量不平衡因子精度的影响
本文主要讨论离散傅立叶变换测量不平衡因子的精度问题。特别地,当信号进行非相干采样时,考虑了采样频率不合适的问题。同时考虑了测量窗口宽度及其形状。所有的分析都是基于解析解以及仿真和实验研究。
