Sancho, José M.2009-09-212009-09-2119851050-2947https://hdl.handle.net/2445/9347A retarded backward equation for a non-Markovian process induced by dichotomous noise (the random telegraphic signal) is deduced. The mean-first-passage time of this process is exactly obtained. The Gaussian white noise and the white shot noise limits are studied. Explicit physical results in first approximation are evaluated.3 p.application/pdfeng(c) The American Physical Society, 1985SorollFluctuacions (Física)NoiseFluctuations (Physics)External dichotomous noise: The problem of the mean-first-passage timeinfo:eu-repo/semantics/article367info:eu-repo/semantics/openAccess
