传统的诱发电位检测法—时间锁定平均法是一种耗时的方法，不适于某些应用。本文介绍一种快速检测诱发电位的方法—Ｍ－序列检测法。文中给出了利用Ｍ－序列检测脑干听觉诱发电位的原理，并介绍了实验系统。理论表明，这项技术能够获得传统平均法（Ｌ＋１）２／４Ｌ倍的检测信噪比，其中Ｌ是序列的长度。在猫和正常人身上所做的试验显示，它比传统的方法能更好地改善检测信噪比，缩短检测时间
The traditional method of evoked potential test - time-averaging method is a time-consuming method, not suitable for some applications. This article describes a rapid detection of evoked potential method-M-sequence detection method. The paper gives the principle of using M-sequence to detect brainstem auditory evoked potentials, and introduces the experimental system. The theory shows that this technique can obtain a detection signal-to-noise ratio of 2 / 4L times the traditional average method (L + 1), where L is the length of the sequence. Experiments done in cats and normal people show that it can better detect signal-to-noise ratio and reduce detection time than traditional methods
