Abstract: This paper deals with the effects of stochastic resonance in some sorts of nonlinear dynamic systems on multi-frequency signal processing in the presence of white or colored noise. By means of tuning system parameters and changing the nonlinear systems, the ability of the systems driven by noise to process a weak signal can be enhanced. We are trying to look for a more effective system to process signals and to find a few systems which have higher effectiveness on signal processing in some circumstances. The numerical simulations strongly support the theoretical conclusions.
