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。

HHT主要内容包含两部分，第一部分为经验模态分解（Empirical Mode Decomposition，简称EMD），它是由Huang提出的；第二部分为Hilbert谱分析（Hilbert Spectrum Analysis，简称HSA）。简单说来，HHT处理非平稳信号的基本过程是：首先利用EMD方法将给定的信号分解为若干固有模态函数（以Intrinsic Mode Function或IMF表示，也称作本征模态函数），这些IMF是满足一定条件的分量；然后，对每一个IMF进行Hilbert变换
