摘　　要：1998年,Norden E.huang等人提出了一种新的非平稳信号的时频分析方法Hilbert-Huang变换,它以瞬时频率为基本量,以固有模态信号为基本信号,与以往的时频分析方法相比有明显的区别,文章主要比较Hilber-Huangt和其他时频分析方法区别,论述了Hilbert-Huang变换的一些优势及其在分辨率上的改善问题。Hilbert-Huang Transform, which was develped by Norden E Huang of NASA in 1998, is a new method of Time-frequency analysis. It takes instantaneous frequency as basic element and takes empirical mode decomposition as basic signal, which has obvious differences with the old methods of time-frequency analysis.The major of this paper,Compared the differences between Hilbert and old methods of analysis, discussThe advantages of Hilbert-Huang and the improvement in its distin-guishability.
