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.

Key words: Empirical Mode Decomposition(EMD); Intrinsic Mode Function(IMF); signal separation; frequency; sinusoidal signal
