摘　　要：本文基于正交小波变换、分析了三类共３０例豚鼠脑干听觉诱发电位信号，表明这种信号经正交小波变换后，不但能够利用近似信号更简单准确地得到传统判别参数。 feature extraction method of BAPE signals was proposed based on the wavelet representation of the signal. We adopted symmetry wavelet here and demonstrated that in wavelet transform domain, not only conventional features but also some new effective feature could be obtained. Thirty samples divided into three types according to their pathology were analysed.
