INVESTIGATION OF STOCHASTIC RESONANCE IN MONOSTABLE SYSTEMS

N. V. Agudov, A. V. Krichigin

Abstract

The phenomena of stochastic resonance is studied in overdamped nonlinear monostable systems driven by a periodic signal and Gaussian white noise. It is shown that the signal power amplification as a function of input noise intensity can be different depending on nonlinearity: it can monotonically grow, decrease and it can reach a maximum at certain value of the noise intensity. Nevertheless, the output signal to noise ratio is shown to be always a decreasing function of input noise intensity.
