“…In the example, the recognition of high arousal degree in the EEG signal for the intention complex task used 14 channels (AF3, F7, F3, FC5, T7, P7, O1, O2, P8, T8, FC6, F4, F8, AF4) are collected by Emotiv headband [6]. In signal processing, a bandpass filter in the EEG signal processing analysis is practically applied to obtain the EEG frequency range from 0.01 Hz until 100 Hz with an approximate amplitude of 100 μV [7]. Then the comprehensive features of EEG signals were extracted into various connectivity functions based on primary frequency bands which are delta, theta, alpha, beta, and gamma [8].…”
