Abstract
External feedback can enhance (or depress) the response of a noisy bistable system to monochromatic signals, significantly magnifying its natural stoc hastic resonance. We compare and contrast a variety of such feedback strate gies, using both numerical simulations and analog electronic experiments. T hese noninvasive control techniques are especially valuable for noisy bista ble systems that are difficult or impossible to modify internally.
