- 实现希尔伯特-黄变换的功能,并带有一段测试数据。希尔伯特-黄变换是使用EMD分解将信号分解为本征模态函数(IMF),然后求得IMF分量的瞬时频率。其对于非稳态和非线性信号具有优良的效果。-The function plot_hht is a realization of the Hilbert-Huang transform (HHT). The HHT decomposes a signal into intrinsic mode functions (or IMFs), and obtain
HHT2
- Hilbert变换只是单纯地求信号的瞬时振幅,频率和相位,有可能出现没有意义的负频率;HHT变换先将信号进行EMD分解,得到的是各个不同尺度的分量,对每一个分量进行Hilbert变换后得到的是有实际意义的瞬时频率。 -imagesc(t,fliplr((1:size(im,1))/(2*size(im,1))),im,[inf,0]) set(gca, YDir , normal ) xlabel([ time ]) ylabel([ normalized f
