| Abstract: | Hilbert-Huang Transform,which was developed by Norden E Huang of NASA in 1998,is a new meth- od of Time-Frequency analysis.The major parts of this method,empirical mode decomposition and Hilbert trans- form,were introduced in detail in this paper.Its end effects,which are produced in the decomposition of empirical mode decomposition processed,and restrained methods are also analyzed.At last,some applied fields and exam- ples of this method are discussed briefly. |

| Keywords: | Hilbert-Huang Transform Empirical Mode Decomposition Hilbert Transform Intrinsic Mode Function End effect |
