Witryna1 cze 2009 · In this paper, an improved EMD method is proposed for measurement and analysis of composite or multicomponent signals. With this new method, composite signals can be decomposed to several IMFs. The IMFs represent the intrinsic and reality feature of the analyzed signal. WitrynaAbstract In this paper, we present a new method for classification of electroencephalogram (EEG) signals using empirical mode decomposition (EMD) method. The intrinsic mode functions (IMFs) generated by EMD method can be considered as a set of amplitude and frequency modulated (AM-FM) signals.
