In this paper, we have investigated the phenomenon of logical stochastic resonance in a trip-well potential system driven by a colored non-Gaussian noise. The effects of a non-Gaussian noise on logical stochastic resonance have been discussed, and we have found that the reliability of the logic operation is dependent on the parameter q that indicates the departure from Gaussianity. The reliable region in the parameter plane of correlation time τ and noise strength D appears and expands with the decrease of q. Furthermore, it has been found that the reliable region in the plane (q,D) expands with the increase of noise color. The phenomenon can be explained successfully by the approach of Fokker–Planck equation.
