Abstract

In this chapter, we analyse the HHT-based characteristics of the instantaneous frequencies (IFs) of the clinical normal, sharp I, and II electroencephalogram (EEG) signals recorded from epilepsy subjects. In addition, we discuss the frequency-energy distributions of the intrinsic mode functions (IMFs), the mean, standard deviation, and maximum, and minimum frequencies of the IFs for the clinical normal, sharp I, and II, EEG signals recorded from epilepsy subjects. The ratios of the energy for several IMFs of the normal, sharp I, and II EEG waves in the δ band to their corresponding total refereed energy were analyzed, respectively.
