中文说明:
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。
English Description:
The function of Hilbert Huang transform is realized with a section of test data. Hilbert Huang transform uses EMD decomposition to decompose the signal into intrinsic mode function (IMF), and then obtains the instantaneous frequency of IMF component. It has a good effect on non-stationary and non-linear signals.
