Abstract
We study the effect of noise-enhanced stability of periodically driven meta stable states in a system described by piecewise linear potential. We find that the growing of the average escape time with the intensity of the noise is depending on the initial condition of the system. We analytically obtai n the condition for the noise enhanced stability effect and verify it by nu merical simulations.
