Default Re: FM "deviation"

Is this the right point in the discussion to bowl in a googly? Namely, that in FM the carrier amplitude reduces with modulation (although the total signal amplitude remains constant) while in AM the carrier amplitude remains constant (although the total signal amplitude varies). I remember being quite shocked, then amused, when I first realised this.

Just when you all thought you were beginning to understand it!!!
