Effect of colored noise on logical stochastic resonance in bistable dynamics.

摘要: Recently, Murali et al. [Phys. Rev. Lett. 102, 104101 (2009)] showed that some noisy nonlinear dynamics could be exploited to design logic gate based on stochastic resonance (SR). In the paper, inspired by al.'s articles, we consider logical (LSR) phenomenon in a bistable system cycling various combinations of two inputs, presence exponentially correlated noise. The effect colored noise LSR is evaluated success probability obtained desired output. major results are presented. First, it shows can changing intensity. output most reliably at an intermediate band. There still plateau performance curve versus As correlation time increases, optimal band shifts higher level and peak degraded from 100% accuracy. Due influence noise, bit low not completely flat. On other hand, measure evolve nonmonotonically as SR-like result time. It actually finite better than delta certain intensities. study might provide example where exist robustly
