Noise-Induced Linearization and Delinearization
The change of the character of the response of a nonlinear system to a low-frequency periodic field induced by external noise is analyzed by means of analog electronic simulation and theoretically. In general, noise of sufficient intensity linearizes the response. For certain parameter ranges, however, an increase in the noise intensity can sometimes have the opposite effect and is shown to delinearize the response. The physical origins of these contrary behaviors are discussed.
