This experimental work was based on our graduate level experiment on nonlinear dynamics of an RLD-circuit. By employing different data-acquisition techniques such as time-series plots, phase portraits, Poincare sections, spectral density plots, and bifurcation diagrams, we aim to observe the varying period of the voltage signal across the resistor. Each of these plots are an attempt to present a clear picture of bifurcation—the point where period-doubling takes place. We want to be able to distinguish higher order periods such as 8T from chaos via these plots. The circuit comprising a resistor, inductor and a nonlinear diode undergoes a universal route while transitioning from successive period doubling stages to chaos and back to periodic behavior. We also implement a method of automating the acquisition of a bifurcation diagram.
