Abstract

We examine the stability conditions for the averaged moment of a harmonic oscillator having a quadratic random mass. The joint action of asymmetric dichotomous noise and an additional periodic force leads to stochastic resonance in this linear system, where the amplitude of the output signal shows non-monotonic dependence on the frequency of the input signal and the characteristics of the noise.
