【Abstract】 The stochastic resonance (SR) is investigated by experiments using an electionic circuit siniulating Duffing system. ft found that a high output signal-to-noise rate (SNR) canbe obtained by varying damping parameter under certain conditions. Applying the theory of adiabatic approximation,the output SNR is obtained analytically considering the existance of large damping.The theoretical predictions are compared with the experimental results.更多还原
