The response of a noisy nonlinear system to deterministic input signals can be enhanced by cooperative phenomena. We show that when one presents two square waves as input to a two-state system, the response of the system can produce a logical output (NOR/OR) with a probability controlled by the noise intensity. As one increases the noise (for fixed threshold or nonlinearity), the probability of the output reflecting a NOR/OR operation increases to unity and then decreases. Changing the…

Realization of reliable and flexible logic gates using noisy nonlinear circuits

It was shown recently [Murali et al., Phys. Rev. Lett. 102, 104101 (2009)] that when one presents two square waves as input to a two-state system, the response of the system can produce a logical

Construction of logic gates exploiting resonance phenomena in nonlinear systems

The conventional LSR paradigm is extended to implement higher-level logic architecture or typical digital electronic structures via carefully crafted coupling schemes and to realize morphable logic gates through the Logical Coherence Resonance in excitable systems under the influence of noise.

It is shown how the input-output correspondence can be controlled by an external exponentially correlated dichotomous noise optimizing the logical response which exhibits a maximum at an intermediate value of correlation time.

Observations show that the reliability of realizing logical operation in the bistable system can be improved through optimizing parameters of dichotomous noise.

Logic signals driven stochastic resonance in bistable dynamics subjected to 1/f noise floor

Abstract. In the presence of 1/fβ noise, we investigate the logical stochastic resonance (LSR) in an asymmetric bistable model driven by various cycling combinations of two logic inputs. The
