Abstract The phenomenon of stochastic resonance (SR) in a linear system subject to bias signal-modulated noise and additive noise is investigated. By the use of the linear system theory, we get the exact expression of the output signal-to-noise ratio (SNR). It is shown that the SNR is a non-monotonous function of the system attenuation parameter, of the signal bias, as well as of the intensities of the signal-modulated noise and the additive noise. In addition, the SNR behaves non-monotonically with the increase of the correlated strength between the two noises
