Extraction of event-related potentialusing weight average / 医疗卫生装备

ABSTRACT

This paper introduces the methods which are to remove spontaneous electroencephalograph(EEG)disturbance from event-related potential(ERP)by using weight average,to develop the arithmetic and analyze it.The results demonstrate that weight average technology has advantages in ERP extraction and noise cancel.Extraction level of biomedical signals is improved by reducing wave distortion and average superposition times.With the development of signal processing,optimized methods removing EEG disturbance from ERP will be put forward.
