The numerical analysis shows 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 effect of signal modulating noise can occur in the stochastic systems.

理论分析表明，正弦信号在系统输出中的数值表现仍为正弦信号，白噪声的效应是维纳过程，较小的系统参数才能使随机共振系统发生信号调制噪声效应。

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] 。
