代码说明:

  emd分解是对原始信号分解得到各个分量的过程,它的核心是通过找出信号的极大值和极小值点拟合出上下包络从而得到平均包络。(The emd decompose each component of the process of decomposition of the original signal, its core is by identifying the maximum and minimum points of the signal fitting upper and lower envelopes in order to get the average envelope.)

  • EMD&VMD
    说明:  通过经验模态分解emd波形分割,将脉冲波形分为多个部分,基于EMD的时频分析方法既适合于非线性、非平稳信号的分析(By empirical modal decomposition emd waveform segmentation, the pulse waveform is divided into several parts, and the time frequency analysis method based on EMD is suitable for nonlinear and non-smooth signal analysis)
