| Abstract: | The limitation of application on small parametric stochastic resonance and big parametric twice-sampling stochastic resonance was studied. The algorithm of self-adopting scanning stochastic resonance has been put forward. Detection of weak signal submerged in strong noise was realized by automatic changing the frequency of signal sampling and adjusting the structural parameter of bistable system, and reached the purpose of engineering application. Experimental study shows that the self-adopting scanning stochastic resonance technique can be applied to engineering practice. |
