| Abstract: | The pulsed
noise in the condition monitoring signal of rotating machinery may lead to the
unsteadiness of the frequency spectrum of the signal, which will directly affect the
accuracy and reliability of the monitoring. A method for rejecting the noise is suggested
in the paper. Experimental results show that the method can successfully reject the noise
and improve the S/N ratio of the signal. |
