摘要：

By adding constant-amplitude pulses to a noisy bistable system, we enhance its response to monochromatic signals, significantly magnifying its unpulsed stochastic resonance. We observe the enhancement in both numerical simulations and in analog electronic experiments, This simple noninvasive control technique should be especially useful in noisy bistable systems that are difficult or impossible to modify internally.
