代码说明:

说明:  通过时域转换为频域,在频域中截取低频部分,去掉高频部分将结果再转换到时域以实现低通滤波的功能。(Through the time domain is converted to frequency domain, in the frequency domain low-frequency part of the interception, to remove high-frequency part of the results and then switch to the time domain in order to achieve low-pass filter function.)

  • waveletentropy
    该程序是基于小波变换的熵谱,用来提取时间序列的周期成分。熵谱相对于小波谱来说在提取周期成分上有一定优势(The program is based on spectral entropy of wavelet transform to extract time series of the periodic component. Entropy is relative to the small spectral component in the extraction cycle, there are some advantages)
