In this paper, besides deriving analytical expressions for probability density function of some nonlinear oscillators, their qualitative behaviors are presented and in analogy with cases with deterministic excitation nonlinear features such as bifurcation and limit cycles are studied. The excitations of oscillators in this paper are external, parametric or mixed and in the form of Gaussian white noise.
