We present the results of an experimental study of the effects of a adding a stochastic binary signal to the input of a nonlinear electronic oscillator. The circuit is a modified Van der Pol oscillator whose bifurcation structure is well understood. For high frequency digital noise added around a Hopf bifurcation the effect observed is a smoothing out of the bifurcation, and a delay in the phenomenological bifurcation point. © 2000 American Institute of Physics.

    In this paper, the strongly resonant bifurcations of a nonlinearly coupled Van der Pol-Duffing Oscillator by the classical multi-scale method are studied. It is shown that there exist periodic motions of a single oscillator, frequency-locking and quasi-periodic motions of two oscillators when...

    Propagating waves in a ring of unidirectionally coupled symmetric Bonhoeffer-van der Pol (BVP) oscillators were studied. The parameter values of the BVP oscillators were near a codimension-two bifurcation point around which oscillatory, monostable, and bistable states coexist. Bifurcations of...

    The dynamics of a van der Pol-Mathieu (vdPM) equation with time delay is considered. The vdPM model can be realized as the governing equation for dust density in a simplified model of dusty plasma. The dynamics of the time-delayed equation is analyzed by separating the timescales of the system...
