| Abstract: | Stochastic Resonance(SR) is a phenomenon that the addition of a low and proper noise can enhance the detection and transmission of weak signals in certain nonlinear systems.Study found that SR can be used to detect weak signals in strong noise background.This paper introduces the mechanism and classical theory of stochastic resonance.Several characteristic quantities of SR that are important to quantify stochastic resonance are presented.This paper also introduces some study cases using SR to detect weak si... |
