Greetings all;
One of the problems that was confusing me recently is that I had replaced
the old samsung crt monitor with a much newer cheap AOC lcd that runs at
1360x724 at best, but under the vesa driver on an ati x1650 video card, it
apparently is running in 1024x768. This results in a

I don't think it is real common, but I can't see any reason it won't
work. You would put RC networks

I just looked at it briefly. Actually not too briefly, but if what I
need is in there (and it might be) it's going to take a bit longer to
find and understand it. The AVR code isn't an issue since I was hoping
to use one of the much faster ARM micro-controllers out there.
Thanks.

My gut reaction to that Jon, is that it would total the amps by turning
into a very low impedance load at the target frequency.
No, that is why you put resistors in series with either the cap or the
parallel LC. My understanding
is that the resistors could be a fairly
