Abstract
Weak signal is a small signal,which is drowned in the noise,and generally with low SNR. Detection of weak signals is very important in engineering application,especially in the fields of physics,electronics and biomedicine. According to the theory of stochastic resonance,noise under certain conditions is conducive to detection of weak signals. The principle of stochastic resonance,stochastic resonance phenomenon in bistable systems and applied research status of stochastic resonance are studied in this paper.关键词
