Stochastic Resonance In Chua’s Circuit Driven By Alpha-Stable Noise

Serpil Yilmaz, Ferit Acar Savaci
In this paper, the stochastic resonance in Chua’s circuit driven by alpha-stable noise has been investigated. Spectral power amplification has been analyzed by changing the characteristic exponent and scale parameters of alpha-stable noise. The results provide a visible stochastic resonance effect in Chua’s circuit and the fading is observed as the noise becomes more impulsive (i.e., smaller characteristic exponent) The simulations reveal that the average time (mean residence
time) spent by the trajectory in an attractor can be varied by changing the characteristic exponent, skewness and scale parameters of alpha-stable noise.
