We describe approximation methods for nonlinear difference, differential and integral systems whose parameters are ergodic stochastic processes. We show that solutions are the sum of an averaged solution and a diffusion process that solves a linear Langevin equation. An application to phase-locked loop networks is described. Reference: A.V.
