Design and Trial Production of Stochastic Resonance Processor using FPGA

Abstract

Stochastic resonance phenomenon improves sensitivity of a signal is under a certain probability by adding noise to a weak signal. The phenomenon might be implemented in electronic circuits, and it was used various fields. For example, the phenomenon was used to detect digital image data in severe shooting conditions. Therefore, we considered if it is possible to construct a stochastic resonance circuit in digital circuits, it can be integrated into various digital devices. In this study, we construct a stochastic resonance circuit with FPGA (Field-Programmable Gate Array), and investigate the change in detection accuracy. As a result, the improvement of the correlation coefficient was confirmed by increasing the number of parallelization.
