I read that this is not difficult by paralleling ADC's or using averaging.
Since the noise generally is symmetric(generally gaussian) by averaging it
will cancel out.
I guess it is more important that the ADC be stable but as long as any
fluxuations are symmetric(such as clock jitter) then averaging should take

The wavelength for 30GHz makes for about a 3.3 picosecond period.

Two dogs, male litter mates, found abandoned down at the barn one
morning in Joelton, Tennessee. About six weeks old and cute as
buttons. Me, "Hunny, can we keep 'em?"
And lotsa guppies.
We need a barn cat to keep the vermin down.

Leave it Johnny, the jackass that accuses others, to claim that what I
stated was on par with his previous claims.
You, Johnny boy, have serious psychological flaws and severe character

Obviously then, they should install loads of gallium phosphide. Green is
supposed to be the brightest percieved color.
Maybe they should start in Sweden.. they'd be more comfortable with the
"Borg" look, right? ;-)
Hmm, monochromatic LEDs are still pretty easy to filter. GaP linewidth
might be 20nm, more than the laserlike sodium doublet, but not as bad as

Two cats and two dogs. (I started with one cat, my wife brought two dogs, and
for parity we adopted a kitten from a next door neighbor. :-) )

Herbie (dachshund, 14-1/2) passed away last September.
So, we don't talk much these days....
However, when he was around, he knew lots and lots of words.
He was also smart enough to know front door or back door when I would
ask if he wanted to go outside.
I finally figured out the determination was made based on whether I

Good syrup will never go bad. If it does mold, just bring it to a boil; good

Re: Let's design a fake Perpetual Motion machine

Perpetual motion is built into the universe, it's a fundamental
property of it.
Of course, limited by its life span.
See: Newton's first.
"Every object in a state of uniform motion tends to remain in that
state of motion unless an external force is applied to it. "
Things move forever as long as they're not disturbed.

Never made a variable frequency generator with a uC before?
it's very easy. Look at DDS technology. Just an old idea with a new
name on it and some alterations to make it possible for a wide range of
output.
With 20 Mhz uC's you can get 1khz sine waves via pwm with no problem
into a padded network that is unity buffered.
