Abstract

•The SR and chaos characteristics of the Duffing system are studied under Gaussian white noise.•The system is used to detect frequency and amplitude of multi-frequency weak signal.•The Lyapunov exponent is used to find the threshold of the chaotic critical state.•The method is successfully applied to detect the boundary voltage amplitude in EIT.
