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.

No, I'll just tell you that you don't understand the material you're
referencing. Much as you have no understanding of mechanical engineering.

You'll tell me that without explaining what you mean, of course...


You ought to stop debating engineering topics Alan. They're obviously
over your head.
LOL
What's funny about that?

LOL

What makes you think that's anything but a dodge? A juvenile one at that.
