Abstract
Evoked potentials (EP) is an important bioelectric signal for studying the neural processes, but it is immersed in very strong background noise. Extraction of EP from a single trial has been a topic of great theoretical and clinical interest. In this paper, a new signal processing method--wavelet transform is introduced and several applications are given.
摘要
诱发电位（EP）是用于研究神经过程的一种重要生物电信号，但它淹没在非常强的背景噪声中。从单次试验中提取EP一直是一个具有重大理论和临床意义的课题。本文介绍了一种新的信号处理方法——小波变换，并给出了几个应用实例。
