| Abstract: | It is a key problem for diagnosing system to acquire fault symptoms. A method of signal mutative symptom extraction is presented, in which the theory of wavelet transform is applied. Moreover, this method is used in fault diagnosis of test turntables. The experimental results show that this method has obvious effect on mutative symptom extraction. |
