Query: High Frequency Stochastic Resonance in Periodically Driven Systems   High frequency stochastic resonance (SR) phenomena, associated with
fluctuational transitions between coexisting periodic attractors, have been
investigated experimentally in an electronic model of a single-well Duffing
oscillator bistable in a nearly resonant field of frequency $\omega_F$. It is
shown that, with increasing noise intensity, the signal/noise ratio (SNR) for a
signal due to a weak trial force of frequency $\Omega \sim \omega_F$ at first
decreases, then {\it increases}, and finally decreases again at higher noise
intensities: behaviour similar to that observed previously for conventional
(low frequency) SR in systems with static bistable potentials. The stochastic
enhancement of the SNR of an additional signal at the mirror-reflected
frequency $\vert \Omega - 2 \omega_F \vert$ is also observed, in accordance
with theoretical predictions. Relationships with phenomena in nonlinear optics
are discussed.
