摘要
在谐波测量实践中提出的以卷积定理为基础的新的加权窗，用以提高窗的消瓣效应和分辨能力，减少泄漏效应，提高频谱分析的精度以及总体的ＦＦＴ处理的效率，展现了新的加权窗函数在电力网络周期信号谐波分析中的应用前景．
A new kind of weight window based on the convolution theorem is proposed after
repeated measurements of the harmonic waves, which will improve the window's eliminating effect
and resolving power, reduce the leakage effect and increase the accuracy of spectral analysis and
the overall efficiency of the FFT process. Vast vistas have been opened up for the application of
the new window function in the electric power network.
