HHT算法实现emd分解，及希尔伯特黄变换，实现瞬时频率瞬时幅值，边际谱的提取。-The HHT algorithm emd decomposition and Hilbert-Huang transform to achieve the instantaneous amplitude of the instantaneous frequency marginal spectrum extraction.

分解后的一些希尔伯特黄变换，边际谱，瞬时能量，瞬时频率。。。很好的，值得一看-Some decomposed Hilbert-Huang transform, marginal spectrum, instantaneous energy, instantaneous frequency. . . Good, worth a visit. .
