| Abstract: | The principle and method of detecting faint characteristic signal based on chaotic oscillator is introduced in this paper. The simulation experiment results show that this method can detect the faint characteristic signal from input signal thought the input signal is very low signal to noise ratio(SNR). The application of the vibration signal measured from rolling bearing indicates that this method is effective. |
