| 摘 要： | 论述了运用小波变换进行听觉诱发电位单次提取的原理，方法和实验分析。结果表明，对单次试验信号，经小波变换及相关分析后，可从带自发脑电干扰的信号中提取诱发电位信号。小波变换分析与传统的叠加平均方法相比，可减少试验次数，缩短检测周期。

| Abstract: | The principle,process and experimental analysis for the single extraction of auditory brainstem potential by wavelet transformation are discussed.The results indicate that,through the wavelet transformation and correlation analysis,the auditory braistem potential signal can be extracted from the signal containing spontaneous brain wave interference by signal test data only.As compared with traditional superposed average method,the wavelet transformation analysis method can considerablly reduce the number of tests and shorten the whole detecting period. |

| Keywords: | auditory evoked potential wavelet transform single extraction correlation analysis |
