Issue Date: | 14-Jan-2008 | Abstract: | We present an experimental study of stochastic resonance in an electronic Chua circuit operating in the chaotic regime. We study in detail the switch-phase distribution and the phase-shift between sinusoidal forcing for two responses of the circuit: one depending on both inter-well and intra-well dynamics and the other depending only on inter-well dynamics. We describe the two relevant de-synchronizatrion mechanisms for high and low frequencies of the forcing and present a method to detect the optimal noise intensity from switch phases which coincides with the one derived from the observation of the signal-to-noise ratio or residence times. | Description: | PACS numbers: 05.40.-a,02.50.Ey.-- 5 pages, 9 figures. | Gov't Doc #: | arXiv:0710.5353v1 [nlin.CD] | URI: | http://hdl.handle.net/10261/6058 |
