摘　　要：本文首次以平均ＥＲＰ和单次ＥＲＰ小波变换系数相关性为基础，设计了小波时频滤波器，可以将单次事件关联电位的Ｐ３波从眼动。A new time frequency filter based on correlation of wavelet transform coefficient between mean ERP and single ERP is presented in this paper. This filter can extract the P3 wave from the background of eye moving and spontaneous EEG activity.

关 键 词：事件关联电位 小波变换 生理实验技术
