By making a numerical analysis of the bistable stochastic dynamical systems, we find that the effect of an input sinusoidal signal is also a sinusoidal signal in the output, and the effect of the white noise is a Wiener process. When the system parameters are small enough, the coupling effect between the sinusoidal signal and the white noise can be largely weakened.

随机共振是双稳系统在周期信号和噪声的作用下表现出来的非线性现象，当系统的非线性与信号和噪声之间存在某种匹配时，通过对系统施加适当强度的噪声，可以提高系统对信号的响应，系统输出的信噪比对噪声强度表现出一峰状曲线[11] 。
