ABSTRACT
This chapter presents a gallery of simple and significant experiments showing the behavior of some interesting nonlinear circuits with the fundamental aim of proposing practical experiences that can directly realize being stimulated to observe and characterize different behaviors and to invent new experiments. The instrumentation required to realize the experiments proposed in the chapter consists of the following equipment: analog or digital multimeter; dual-voltage power supply; waveform/function generator; and oscilloscope. The chapter presents a state-controlled cellular neural network (SC-CNN) implementation of a memristive device whose nonlinearity is responsible for the chaotic behavior of a simple nonlinear circuit, namely the memristive Chua's oscillator. In the experiments, the chapter shows the effect of a Gaussian noise injected into one node of the Chua's circuits network on the emerging global behavior and, especially, on synchronization, showing that under some conditions noise leads to significant changes in the whole network dynamics.
