Fecha de publicación: | 1-ene-2007 | Editor: | Elsevier | Citación: | Physica A 374, 46-54 (2007) | Resumen: | Here we present a study of stochastic resonance (SR) in an extended FitzHugh Nagumo system with a field dependent activator diffusion. We show that the system response (here measured through the output signal-to-noise ratio (SNR)) is enhanced due to the particular form of the non-homogeneous coupling. Such a result supports previous ones obtained in a simpler scalar reaction-diffusion system and shows that such an enhancement, induced by the field dependent diffusion -or selective coupling-, is a robust phenomenon. | Descripción: | 9 page | Versión del editor: | http://dx.doi.org/10.1016/j.physa.2006.06.026 | URI: | http://hdl.handle.net/10261/6135 | DOI: | 10.1016/j.physa.2006.06.026 | ISSN: | 0378-4371 |
