We present a method to construct a modulation frequency response curve for bistable systems in the presence of noise. To this end, a small sinusoidal modulation is applied to the system such that it switches between its two stable states. The response curve we construct yields information on the nature of the physical mechanism underlying the switching process and is furthermore comparable to the standard response curves of linear systems. Our semianalytical approach, which only needsdoi:10.1103/physreve.70.046214 pmid:15600502 fatcat:jdgquwjgnbf5fn3zh3jxlygpkq
