Time-frequency analysis is used to detect high-frequency components on intracranial and scalp EEG (Kobayashi et al, 2010; Zijlmans et al, 2017). However, analysis programs are not always available in clinical situations. We introduce a method to detect high-frequency components without special analysis programs. EEG activity shows sinusoidal waveform with stable / evolving frequency and stable / evolving amplitude. On the other hand, electromyogram (EMG) is sharply contoured with variable frequency [...]
