I think I'm hearing the electrical noise from that up here on my SSB
radio. :-)
Actually, if you know the secret, it's pretty simple:

Eisboch's probably got a couple of these out back in the shed. Just
hook it up to the old Brinkman
and away you go:

Being the nerd I am, I have to comment:
Pulse width modulation is how the "Super Audio" CD's were made and
are
vastly superior to conventional CD's in terms of fidelity, dynamic
range and sound reproduction. Don't hear about them much anymore
due
to the general interest in quantity over quality in music
reproduction and storage. I still have a super cd player hooked up
to a fairly decent sound system. "Sultans of Swing" by Dire
Straits
never sounded so good. It really shines if you get in the mood for a
little "hi brow" classical music as well.
The sputter system? Yep. We built many of them over the years for
various commercial, military and R&D purposes. Applications included
the production of CDs, heart/artery stents, automotive components,
and sputtered thin film gauges on jet engine turbine blades. The
automatic rain detectors used in the windshields of GM cars were
developed in one of our sputter systems.
Memories.
So it won't serve to modulate my smoker temperature.
Crap.

Well not a Super CD player, that's for sure. But an industrial type
SCR type controller would work. It would have to be rated for about
2500 watts or more for a typical electric stove top element. Light
dimmers are typically 600 watts and are too small. There are two
basic types, "phase angle firing" and "zero crossing". One is
electrically quieter than the other but I don't remember which one.
