Stochastic Resonance in Electrical Circuit(Session I : Cross-Disciplinary Physics, The 1st Tohwa University International Meeting on Statistical Physics Theories, Experiments and Computer Simulations)

Abstract

We studied experimentally on SR using electrical circuits. to investigate effects of the potential profile as well as the superposition of two different periodic signals as a modulation signal. Results are summarized as follows : (1) Asymmetric potential profile strongly influences the aspect of SNR. (2) SR suppresses the mode coupling which produces harmonics. As no theoretical work has been done in this direction, the detail will be reported in the near future.
