Subthreshold Signal Enhancement in a Space-Dependent Damped Van der Pol-Duffing Oscillator via Vibrational Resonance
This paper presents a numerical study of a subthreshold signal enhancement in a Van der Pol-Duffing oscillator, via the phenomenon of vibrational resonance. The oscillator describes a particle motion in a bistable periodic potential, influenced by space-dependent damping and excited by an external bichromatic excitation. Temporal and spectral analy...
