摘要
用数值方法研究了白噪声背景下的双频率信号在双稳系统中的随机共振行为，计算结果表明：利用非线性系统的随机共振。
Using numerical simulation,we establish the possibility of realizing the stochastic resonance phenomena in bistable systems simulted by white noise when it is driven by two frequency signals.It is shown that the application of stochastic resonance in nonlinear system can lead to an improved signal-noise ratio.
