摘要
在易于不对称的两分的噪音、趋于增加的一个推迟时间的双稳态的系统和添加剂白人噪音的随机的回声被调查。用小时间延期近似，我们获得 signal-to-noise 比率(SNR ) 的表示。SNR 是推迟的时间的一个非单调的函数，这被发现，输入的振幅方形波浪的信号，以及两分的噪音的不对称现象。另外， SNR 与系统参数非单调地变化，与紧张趋于增加并且添加剂噪音，以及与两分的噪音的相互关联率。[从作者抽象]
Stochastic resonance in a time-delayed bistable system subject to asymmetric dichotomous noise and multiplicarive and additive white noise is investigated. Using small time delay approximation, we obtain the expression of the signal-to-noise ratio （SNR）. It is found that the SNR is a non-monotonic function of the delayed times, of the amplitude of the input square-wave signal, as well as of the asymmetry of the dichotomous noise. In addition, the SNR varies non-monotonously with the system parameters, with the intensities of the multiplicative and additive noise, as well as with the correlate rate of the dichotomous noise.
