Optimal improvement in bistable measurement device performance via stochastic resonance

The notion of noise-activated systems has been well known since the 1950s. A number of natural phenomena have been investigated by means of this theor y and an improvement in the performance of several systems has also been ac hieved. Recently the stochastic resonance (SR) phenomenon was introduced as an innovative approach for both understanding the behaviour and improving the performance of several classes of systems. In the present work some new results regarding the influence of forcing signal parameters on the persis tence of the SR condition are given. Both theoretical results and numerical simulations have been carried out to emphasize the suitability of the prop osed noise tuning methodology.
