When you modulate a carrier, you are essentially multiplying two sine
waves toegther

sine A. sin B = 0.5 .(cos (A-B) - cos(A+B))

This implies that you shouldn't see the carrier frequency at all,


** Because it is the wrong formula.

As if Phil Allison knew the "right" formula - the cantankerous poseur
would have posted it if he did.

If fact, given the range of applications for amplitude modulation,
there is no one "right" formula. The one I posted is probably the right
one to answer the OP's question, but that's a level of comprehension
that Phil can't manage.
