Stochastic resonance (SR) enhances the nonlinear system behavior with the assistance of noise, including the sensitivity and selectivity of the response to the exterior stimulus. The energy-transfer mechanism makes the weak information revealed in the output spectrum, while the time-waveform is distorted. The investigation on the signal recovery in bistable SR was carried out. It helps the SR technique develop and spread in the engineering applications.
