But, what would *they* know? It's just Cornell University...

So you think a DAC puts out discrete voltage levels? Only if you
remove the circuitry that smooths its output into sine waves.

As I already demonstrated in another post, there are DACs that don't
have any smoothing circuitry.

Then you demonstrated an incomplete DAC because you don't understand the
subject.

Tell these folks that:

Tell wikipedia:

And tell it to the university whose link I provided you before.


You ought to stop debating engineering topics Alan. They're obviously
over your head.

LOL

What's funny about that?
