Complex Dynamics in Digital Nonlinear Oscillators: Experimental Analysis and Verification

A specific topology of Digital Nonlinear Oscillators (DNOs) has been implemented by using commercial off-the-shelf digital components to experimentally verify and demonstrate the capability these circuits support complex dynamics, independently from their implementation technology. In detail, a direct experimental evidence DNO dynamical behavior is presented at analog level with bifurcation diagram analysis, investigation periodic chaotic attractors, stability. The autonomous circuit investigated as source entropy, adopting different figures merit, including Lempel–Ziv Complexity, evaluate dynamics measured under operating conditions.
