We study linear responses of a stochastic bistable system driven by dichotomic noise to a weak periodic signal. We show that the effect of stochastic resonance can be greatly enhanced in comparison with the conventional case when dichotomic forcing is absent, that is, both the signal-to-noise ratio and the spectral power amplification reach much greater values than in the standard stochastic resonance setup.
我们研究了由二分噪声驱动的随机双稳系统对弱周期信号的线性响应。我们表明,与不存在二分强迫的传统情况相比,随机共振的效应可以大大增强,也就是说,信噪比和频谱功率放大都比标准随机共振设置中的值大得多。
