摘要

利用经验模态分解(Empirical Mode Decomposition

简称EMD)方法对由两个正弦线性叠加而成的信号进行分离处理，研究正弦信号的频率和振幅对EMD分离效果的影响.通过多组实验得出，两正弦信号的频率相差越大或振幅相差越小， EMD分离效果越明显.

Abstract

With the method of the Empirical Mode Decomposition (EMD)

it studied the separation of the signals formed through linear superposition of two sinusoidal signals. Furthermore

it analyzed how the frequency and amplitude of the signals can affect the result of separation . Multiple experiments show that the bigger difference in frequency or the smaller difference in amplitude between the two signals there is

the more obvious the separation effect is.
