方波和非对称双值噪声作用下的熵随机共振研究
EntroPic Stochastic Resonance Driven by Square-Wave Signal and Asymmetric Dichotomous Noise
摘要
Abstract
The entropic stochastic resonance( ESR)in a confined system driven by asymmetric dichotomous noise, white noise,and a square-wave signal is investigated. Under the adiabatic approximation condition,the expression of the output signal-to-noise ratio( SNR)is obtained. It is shown that the SNR is a non-monotonic function of the strength and asymmetry of the dichotomous noise,of the intensity of the white noise,and the amplitude of the square-wave signal. Moreover,the SNR varies non-monotonously with the increase of the parameters of the confined structure. The influence of the correlation rate of the dichotomous noise on the SNR is also discussed.关键词
