摘要
Abstract
The stochastic resonance phenomenon in a harmonic oscillator with fluctuating intrinsic frequency by asymmetric dichotomous noise is investigated in this paper By using the random average method and ShapiroLoginov formula, the exact solution of the average output amplitude gain (OAG) is obtained. Numerical results show that OAG depends nonmonotonically on the noise characteristics: intensity, correlation time and asymmetry.The maximum OAG can be achieved by tuning the noise asymmetry and or the noise correlation time.关键词
