基于FFT方法对微小信号3D分析研究

Analysis on small signals in 3D mode based on FFT method

为了全面准确地分析微小信号,引入基于FFT技术的三维方法,利用LabVIEW2011高级开发者工具包编程设计,实现将微小信号从一维显示转换成三维能量谱的形式。使用所设计的程序成功实现对微小信号的准确分析。采用该方法可以实现对于微小信号的全面研究。

In order to analyze small signals more comprehensively and accurately, 3D method based on FFT technology is introduced.Designed the programs by the way of LabVIEW2011 developers paramount tool-kit, at last realized to change one-dimensional small signals into the form of 3D energy spectrum.We have successfully used programs to realize analysis on small signals.Using the method described above can realize comprehensive analysis on small signals.
