摘 要：正 Normally EEG-signatures are analyzed by transferring the time signal of the electrodes into the frequency domain by a common FFT- or wave-let-transformation. As we will show in this paper, better and faster results can be obtained, if instead of these algorithm the FD-operation is applied to the pure time-signal and further on a DAS-calculation for eliminating the noisy contributions is done. Specially we will compare the signatures of some epilepsy events analyzed by common signal analysis and by the class-oriented DAS- and FD-operations.
