| Abstract: | The basic method of adaptive signal processing and the principles of canceling are introduced. The interference canceling is proved by processing sines signal and sines noise signal with this method. In the processing of the vibration signal picked from cylinder cover of PZ12V190B diesel engine, the adaptive signal is canceled by taking the no working stroke signal as canceling signal. This method can get good results in restraining noise and getting effective signal. |
