Abstract: 

We investigate bistable oscillator under the influence of additive, white and colored, noise. We have found noise-induced bifurcations that consist in a qualitative change of stationary distribution of oscillations amplitude. In the region of bimodal distribution the effect of coherent resonance takes place both for white and colored noise.

Key words: 
noise influence
stochastic bifurcation
bistable oscillator
coherent resonance
