  We investigate the effects of quenched disorder on the coherent response in a
driven system of coupled oscillators. In particular, the interplay between
quenched noise and periodic driving is explored, with particular attention to
the possibility of resonance. The phase velocity is examined as the response of
the system; revealed is the enhancement of the fraction of oscillators locked
to the periodic driving, displaying resonance behavior. It is thus concluded
that resonance behavior may also be induced by quenched disorder which does not
have time-dependent correlations.
