摘要
诱发脑电是研究大脑高级神经过程的一个重要电信号。而从背景噪声中一次提取出诱发电位具有非常重要的实用价值。本文介绍了新兴的小波技术中多分辨率分析方法及其在诱发电位分析和提取中的应用。
Evoked potentials(EP) is an important bioelectric signal for studying the neural processes,but it isimmersed in very strong background noise. Extraction of EP from a single trial has been a topic of great theoreticaland clinical interest. In this paper,a new signal processing method-wavelet transform is introduced and several applicationsare given.
