以双稳系统为研究对象,探讨了影响和产生双稳随机共振的参数选择特性.双稳系统参数和二次采样频率参数有着内在的物理联系,它们的改变都会引起势垒、势阱间距和粒子跃迁速率的改变,并使噪声能量相对重新分配,进而影响随机共振效果.根据随机共振的参数选择规律,可通过适当的参数选择来得到最佳的随机共振状态,为后续数据处理奠定基础.
The bistable system is chosen as the research object to study the parameter selection characteristics that affect and generate the bistable stochastic resonance.The bistable system parameters and the subsampling frequency parameters have intrinsic physical connection, and their changes will cause the barrier, potential well spacing and Particle transition rate and the relative redistribution of noise energy, which in turn affect the stochastic resonance effect.According to the parameter selection rules of stochastic resonance, the optimal stochastic resonance can be obtained by proper parameter selection, which will lay the foundation for subsequent data processing.
