The dynamics of a bistable system resulting from the action of several periodic perturbations and noise is studied. The response of the system at combination harmonics and the changes in the response caused by high-frequency modulation and a constant field that removes the degeneracy in the bistable system are calculated. The mixing of harmonics is investigated experimentally in an iron garnet thin film. It is shown that the higher harmonics exhibit behavior characteristic of stochastic resonance and that the form and symmetry of the dependence of harmonics on the constant field removing the degeneracy can be used to determine the characteristics of a bistable system with respect to its response to external periodic modulation.
