The vibrational resonance in a biased monostable system subject to multiplicative and additive white noises and subject to one high-frequency (HF) and two low-frequency (LF) periodic forces is investigated. Under the adiabatic condition, we obtain expressions for the signal-to-noise ratio (SNR) with respect to the LF signal. It is shown that the SNRs of the fundamental harmonic and the higher harmonics are non-monotonic functions of the amplitude and frequency of the HF signal. The SNRs vary non-monotonically with the growth of the strengths of the multiplicative and additive noises. The dependence of the SNRs on the system bias is investigated.
