title: [A 40 Hz event-related potential detecting system based on correlation-threshold method].
abstract: A 40 Hz 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 exploits the correlation--threshold method proposed by us to cancel the muscle artifacts. We also realizes the automatic control of experiment procedure and statistical data processing in microcomputer.
