本文主要研究了时窗函数谱对信号谱估计的影响;时窗函数谱的特性分析以及利用FFT算法直接计算时窗函数谱的方法。
This paper studies the effects of the data window spectrum on the estimation of the signal spectrum
discusses the method of direct computation of the data window spectrum by FFT algorithm
and introduces some parameters characterizing the data window spectrum and their computation. Also analysed here are the spectral characteristics of some common data windows.
