| Outline of Final Research Achievements |
This study conducts laboratory measurements and numerical experiments on mixed-mode oscillations (MMOs) generated in an extended BVP oscillator. According to our numerical results, the waveform of MMOs is significantly distorted and MMOs are frequently submerged by chaos subjected to an extremely weak periodic perturbation. The numerical results show that MMOs under weak perturbation generate a rich variety of interesting phenomena. Furthermore, the breakdown of MMOs into chaos is observed in experimental measurements. However, chaos via MMOs breakdown is not explained by a white Gaussian noise exiting in real circuits, but is generated owing to a slight drift of DC voltage source.
