Currently, frequency bands not more than 40Hz are usually used to perform mental tasks classification in Brain-Computer Interface systems. In this study, by using Keirn's EEG data, we studied the effects of ten 10Hz-wide subbands between 0 and 100Hz on mental tasks classification. Features were computed in frequency domain as the sum of weighted power spectral value in each subband at each channel (C3, C4, P3, P4, O1, and O2). Fisher's linear discriminant was used to perform task-pairdoi:10.1109/iembs.2005.1615695 pmid:17281465 fatcat:ci5ufx623bhglcmexcs5x5vavi
