Application of HHT to different mental tasks in EEG analysis
HHT方法在不同思维作业脑电信号分析中的应用

The non-linear, non-stationary signal processing method named Hilbert-Huang Transformation (HHT) and its characteristics were introduced, and it was applied to the different mental tasks in EEG analysis. The results indicate that different mental tasks in EEG have different Hilbert-Huang spectrums and Hilbert marginal spectrums, which proves HHT to be a feasible method on EEG analysis.
