Two Stochastic Resonances Induced by Two Different Multiplicative Telegraphic Noises for an Electric System

In this paper, an electric system with two dichotomous resistorsis investigated. It is shown that this system can display twostochastic resonances, which are the amplitude of the periodicresponse as the functions of the two dichotomous resistorsstrengthes respectively. In the limits of Gaussian white noise andshot white noise (i.e., the two noises are both Gaussian whitenoise or shot white noise), no phenomena of resonance appear. Byfurther study, we find that when the system is with three or moremultiplicative telegraphic noises, there are three or morestochastic resonances.
