摘　　要：用数值方法研究了随机共振(SR)系统.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.仿真实例验证了分析结果.The stochastic system is studied numerically. 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. The simulated examples prove the analysis results.
