ABSTRACT
Complex Morlet wavelets, as a wavelet function, is most commonly used in the time-frequency analysis of EEG signal and in the extraction of the instantaneous power and phase. This article explains how to use the Morlet wavelet transform for obtaining EEG's alpha wave energy distribution over time, and how to use the EEG data of mental arithmetic experiment for obtaining the changes of the alpha wave duration.
