Abstract
A model of an overdamped Kramers oscillator perturbed by strong multiplicative Gaussian noise and a weak periodic signal is studied theoretically and experimentally. It is shown that under certain conditions such a system demonstrates on-off intermittency and sensitivity to very weak periodic signals, making possible many-fold (experimentally, by two orders of magnitude) amplification of the signal amplitude.
