Stochastic resonance control based on vibration resonance

The dynamic characteristics of the non-linear bistable system subject to the action of high and low frequency signals were analyzed. The analytic formulation of the relationship between the parameters of high frequency signals and the SNR, spectral power amplification (SPA) of the bistable system output was presented. The stochastic resonance control method based on vibration resonance was proposed. The theoretical analysis and numerical simulation showed that the SNR and SPA of output signal of the bistable system can be controlled effectively by adjusting the amplitude and frequency of the high frequency signal.
