Signal processing method is a important part of the basic technology at the present mechanical equipment fault. The precise degree of 下载后可任意编辑analysis result is the key factor of whether the diagnostic is success or not. Study about the spectrum analysis is one of the mainly develop directions. However, DSP is basiclly from two respects to solve the problem of signal processing: one is time-domain, the so-called digital filter; another is spectrum-domain, the so-called spectrum analysis. The passage is mainly introduced FFT and DFT, by studying about the algorithm of FFT and DFT, studying deeply from the basic and learning, grasping the key of FFT algorithm. By learning the working principle of...
