The frequency domain viewpoint is already well covered both here and later. By removing the confusing word "carrier" from the text it should be clear that it is the composite wave whose amplitude changes even while from the frequency domain viewpoint the "carrier" is constant.

If this is not clear perhaps a better wording is needed, but the change that was made isn't helpful. Tag: Undo
