چکیده انگلیسی
In this paper, we consider the phenomenon of stochastic resonance (SR) in an asymmetric bistable system with coloured noises and periodic rectangular signal. Expression of the signal-to-noise ratio (SNR) has been obtained under the adiabatic limit. We investigate the effect of any system parameter (such as p, q, r, τ1, τ2) on the SNR. The plot of SNR–τ1 shows SR for some values of the additive noise self-correlation time τ2, but not for the whole range of τ2. The system bias r suppresses the SNR. When the intensity of additive noise q is increased, the SR phenomenon disappears in the plot of SNR–p, but the plot of SNR–q presents SR for almost all values of the multiplicative noise intensity p.
