| 英文摘要 | The parameter mismatch (diversity) effect is numerically and theoretically studied in a model of an ensemble of coupled electronic circuit system and the diversity-induced resonance is observed, i.e., the system response to an external subthreshold signal is optimized for an intermediate value of the diversity. In this coupled system, the diversity is represented by a negative conductance with a bounded random distribution for each circuit module. We find that the diversity-induced transition, which forces the system from monostable to bistable, is of key importance for the emergence of resonance. An order parameter expansion theory and a reduced theory are used for analysis. All these findings suggest that diversity-induced resonance can be more generally observed, such as in monostable media and in experimental systems. (C) 2010 Elsevier B.V. All rights reserved. |
