Abstract
A digital method for the estimation of amplitude and phase of the EEG is introduced on the basis of the in-phase and quadrature-phase digital band-pass filters. Applicability of this method to measurements of the EEG changes due to a single photic stimulation is investigated in comparison with the method of complex demodulation. Both methods are found to be useful for measurements of changes in the alpha activity and found to provide similar results. A relation between the filter band-width and the estimated amplitude or phase variations is examined. An attempt is made to detect the peak frequency shifting due to a single photic stimulus.
