| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Stochastic resonance (SR), a phenomenon that signals can be enhanced with especial noise strength in a non-linear system, is focused as a method of sensitively detecting weak signals in a heavy noise environment. In this work, in order to sensitively detect high-speed aperiodic signals, a non-linear circuit based on overdampd Langevin equation and simple bistable potential is designed and experimented. In the results, SR phenomenon was confirmed and signal detecting ratio was improved at aperiodic signal of 10 to 100 kb/s bit rate when signal-to ratio is below 1. The higher speed of the designed circuit can be expected by increasing integrator gain of the main element in the non-linear circuit. | |
