摘要：

A periodically driven bistable system is considered in the region of validity of a two-state hopping approximation. In the limit of weak noise the hopping process becomes discrete not only in space but also in time so that an explicit evaluation of the autocorrelation function becomes possible. This function turns out to be a non-analytic function of time leading to a rather peculiar structure of the power spectrum. Results are compared with numerical and experimental data.
