It is demonstrated that modulation-induced negative differential resistance can survive in the presence of noise and inertia. In the limit of large periodic forcing, by perturbing about the overdamped noise-free system, analytic predictions for the effects of weak noise or small inertia are obtained. These are shown to compare well with the results of detailed numerical simulations.
