Effect of Number of Input Signals on Chaos Synchronization by Applying Zero-dispersion Nonlinear Resonance

In this paper, we report a circuit experiment that demonstrates the effect of the number of input signals on chaos synchronization by applying zero-dispersion nonlinear resonance (ZDNR). The input signals are obtained by generic input–output analysis and the ZDNR theory. In this way, the evolution of chaos synchronization can be observed from our experimental results, that is, two chaotic systems change from phase locking to complete synchronization when the number of input signals of ZDNR increases from one to three. Additionally, a circuit implemented utilizing the ZDNR technique can be applied to sensor circuits to detect specific desired signals.
