| Abstract: | This paper introduced the basic principle of stochastic resonance(SR) and demonstrated SR phenomenon in symmetric bi-stable system by numerical simulation.Then,SR was applied to detect weak signal in a stronger noise background.The results obtained show the effectiveness of the detecting method based on SR. |
