Experimental and numerical observations of reviving oscillations from amplitude death (AD) in two coupled mismatched nonlinear electronic circuits are described. The inclusion of processing delay in the coupling node of the coupled Chua’s oscillators creates a memory of the past state for a finite time duration. Similarly, the fractional order dynamical system has a memory function and remembers the past state of the system. We show that these memory functions are responsible for the reviving and sustained oscillations in the coupled oscillators.
