| ABSTRACT |
| In this study, electroencepharogram(EEG) model was proposed for generating time series that represents the characteristics of EEG accurately. The alpha and beta waves were represented by sinusoidals with fluctuating amplitude, and slow waves (delta, theta waves) were represented by sinusoidals with fluctuating amplitude and frequency. The model parameters were determined by minimizing error between the power spectrum of EEG and the theoretical power spectrum of model derived in this study. The features of time series of the constructed model were compared with those of the raw EEG, and satisfactory results were obtained. |
