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

摘要

In this paper,an electric system with two dichotomous resistors is investigated.It is shown that thissystem can display two stochastic resonances,which are the amplitude of the periodic response as the functions of thetwo dichotomous resistors strengthes respectively.In the limits of Gaussian white noise and shot white noise(i.e.,thetwo noises are both Gaussian white noise or shot white noise),no phenomena of resonance appear.By further study,we find that when the system is with three or more multiplicative telegraphic noises,there are three or more stochasticresonances.
