Abstract:
A 40Hz event related potential(ERP)detecting system is introduced here. The system employs the elliptic—type filters which have excellent edge features to extract signals of narrow-band frequency . It e xploits the correlation—threshold method proposed by us to cancel the musc1e ar tifacts. We also realizes the automatic control of experiment procedure and stat istical data processing in microcomputer.
