We study the mobility of an overdamped particle in a periodic potential
tilted by a constant force. The mobility exhibits a stochastic resonance in
inhomogeneous systems with space dependent friction coefficient. The result
indicates that the presence of oscillating external field is not essential for
the observability of stochastic resonance, at least in the inhomogenous medium.
