I know this, but how does it relate to resonance in physical systems?

E.g. imagine a rigid pendulum driven by a sinusoidal torque at its pivot point. Which signals are multiplied here??

Mixers are physical systems. The precise words for the distinction you are trying to make is between linear and non linear systems.
