Abstract :
This paper presents stochastic resonance of a bistable system. It aims at solving weak signals problem in the engineering community. It studied utilization of stochastic resonance in heavy background noise in order to extract a useful signal from noise. Two methods of stochastic resonance are introduced in the paper.
