A three-dimensional non-autonomous conservative chaotic system based on cross-phase-coupled oscillators: Theoretical analysis and electronic realization

These are experimental time series for an electronic chaotic oscillator grounded on a non-Hamiltonian conservative 3D ordinary differential equation system. Representative waveform recordings, as well as parametric sweeps, are provided. Board design materials are also given, but it should be kept in mind that they are only representative, and the actual component values used in the experiment are those that are reported in the publication referenced below; some patches also need to be applied. These materials are made available to support the replication of the results reported in the associated publication, as well as any further public-domain academic research in the field of neural dynamics, nonlinear electronic circuits, and related aspects, in compliance with the specified license terms and all applicable legal clauses. For any questions regarding these data, the corresponding author of the publication referenced below should be contacted.
