EEG Complex Demodulation

The Complex Demodulation transform continuously transforms the EEG signal by means of

mathematical methods in such a way that the resulting signal consists only of frequencies

that lie in the defined range. Unlike the Fast Fourier transform, only a specific frequency band

can be extracted. The advantage of this transform is that it also works at high speed on non-segmented

data and that the output of each channel is in turn a continuous channel.
