Ed,
In my scope observations, I don't see a Dirac delta function
waveform (unity energy per frequency with infinite bandwidth), but I
do see a simple beating between 2 close frequencies: say 8 to 10
cycles of the "carrier frequency" between the (AM) modulation
frequency notches;) Just think of an AM carrier with 8 to 10 cycles
of the carrier frequency for each modulation cycle.
This is my interpenetration of John's post.
