This paper puts forward a new way of analyzing mutual vertical dynamic signal - pass holospectrum.
本文提出了一种相互垂直的动态信号分析的新方法——通频全息谱。
However, the accuracy of phase, amplitude and frequency are basis of the holospectrum. The values are inaccuracy through the traditional DFT.
然而,精确地求解相位、幅值及频率是作全息谱的基础和前提,基于传统DFT方法是不能得到精确的值。
