摘要：
Stochastic resonance (SR) in an overdamped linear system with periodically modulated noise is studied. The explicit expressions of the first two moments and signal-to-noise ratio (SNR) are obtained when we introduce the asymmetric dichotomous noises to the system. Through analyzing the SNR, we find the bona fide SR and conventional SR. Meanwhile, the effects of the asymmetry and correlation time of the multiplicative noise and cross-correlated noise intensity on the SNR are discussed.
