Abstract:Vibrational resonance in the canonical Chua’s circuit with a smooth
cubic nonlinear resistor is investigated by an analog circuit experiment
and a dynamical model. When other parameters are fixed, changing the
amplitude and the frequency of the high-frequency signal can make the
system’s response amplitude to the low-frequency weak signal exists a
wide peak. The phase diagram of the system will transition from a
single-scroll attractor to a double-scroll attractor when the amplitude
of the high-frequency signa… Show more
