Abstract

The phenomenon of stochastic resonance in an over-damped linear system with random system parameter is investigated. An explicit expression of the mean output-amplitude-gain (OAG) is obtained by using linear-system theory. It is shown that the OAG of the noisy system can be larger than that of the noise free system, and the OAG is a non-monotonic function of the frequency of the drive signal as well as the strength and the correlation time of the colored noise. In addition, the effect of the system parameters on the OAG is discussed
