| 摘 要： | 伪随机序列技术作为一种快速检测诱发电位的技术已得到重视。本文主要对几种常用序列Ｍ序列、巴克序列和格雷互补序列等应用于诱发电位检测时的性能进行研究，分别给出了它们的解卷积算法及用于诱发电位检测时相对于平均法的信噪比改善倍数。理论及实验表明，Ｍ序列在检测信噪比改善方面较另两种序列好。 |

| Abstract: | Performance of 3 kinds of sequence-(M sequence, Barker sequence and Golay complementary sequence) were studied on being applied to EP measurement. The deconvolution algorithms and the SNR improvement compared to averaging technique were also given. Both theoretical and experimental results showed that M sequence gave the best performance in SNR improvement. |
