In the case of the bell, the bell selects the frequencies near its

must select from those harmonics.



Not even wrong.

The response is the convolution of the forcing function against the
natural one.

Not if it's an oscillator, and not if it's nonlinear. A pipe organ is
both.

Uh? You're tip-toeing thru the tulips there, John. In an oscillator
the forcing function IS the oscillator non-linearity.

Don't get me started on Lyopanov ;-)
