Detection and Circuit Realization of Weak Periodic Signal Based on Chaos Oscillator in Mechanical Fault Diagnosis

Chaos is common in nature, in recent years, chaos theory has been concerned in variousfields for its unique performance. Chaos system can detect the weak periodic signal under strongnoise based on its sensitivity to small periodic signal and its immunity to noise, thus makes itsfoundation in the field of signal detection. This paper is carried

Research on Weak Signal Extraction in a Strong Noise Environment Based on Wavelet Analysis

The reliability of experimental data plays a vital role on the model parameter identification, but there exists noises in all systems. How to improve the authenticity of the experimental data is particularly important. Often, the useful signal is relatively weak and submerged in strong noise, so more attention has been paid to the problem of
