| Abstract: | In this paper,we discuss the effects of error feedback driven by an aperiodic signal on the output of a bistable nonlinear system with stochastic resonance.Firstly,the potential function and the dynamical probability density function are derived.Then,to measure the performance of the bistable nonlinear system in the presence of a binary random signal,the bit error rate defined by the dynamical PDF is employed.Finally,the results are demonstrated by theoretical analysis and simulation.The goal of this paper ... |
