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.
