Driving a nonlinear system with a harmonic signal can yield subharmonic combination resonances as well as superharmonic resonances. These undesired responses can be considered “noise” in the response. Analogous to active noise control in the acoustics world, a signal 180° out of phase with the undesired response, at the appropriate level, can effectively cancel the undesired response.
