  We propose here a delay differential equation that exhibits a new type of
resonating oscillatory dynamics. The oscillatory transient dynamics appear and
disappear as the delay is increased between zero to asymptotically large delay.
The optimal height of the power spectrum of the dynamical trajectory is
observed with the suitably tuned delay. This resonant behavior contrasts itself
against the general behaviors where an increase of delay parameter leads to the
persistence of oscillations or more complex dynamics.
