| Abstract: | The stochastic resonance is investigated by experiments using an electronic circuit simulating a Duffing system. It has been
found that a high output signal-to-noise rate can be obtained by varying damping parameter under certain conditions. The deviations
between the experimental results and the adiabatic theory are presented.
