The Lorentz distribution characteristics of the stochastic resonance spectrum of the bistable system are studied, and it is found that the stochastic resonance spectrum can be identified in the low-frequency region where the spectral distribution energy is more concentrated.The quadratic sampling stochastic resonance The spectral characteristics of weak signal detection in strong noise as an example, described the specific application of resampling stochastic resonance technology
