WO-2016025724-A1 chemical patent summary. High frequency oscillations (HFOs) are automatically detected in electroencephalogram (EEG) signals and analyzed to assess whether they are predictive of the onset of a neurological dysfunction in a subject or an indication of nonneurological electrical activity or noise in the EEG signal.

In this study, the input signal passes through the low-pass filter G(n) and the high-pass filter H(n), both of which have a cut-off frequency of one-quarter of the sampling frequency. In the first step of DWT decomposition, the low-frequency approximation coefficient A1 and detail coefficient D1 are obtained, and then, the output A1 is fed to ...
