[EE] 24-bit A/D. Are We in the Twilite Zone Here?

This works quite well. We use it to get better resolution on communication
signal levels over RF.

I think I have the general idea of what you are talking about here.
>From information theory, encryption works because you can take a
non-random bit stream and XOR it with a random stream, and the result
comes out random. Likewise, I have read that you can add a small
amount of random noise to an image that has non-random hash on it,
like streaking, banding, washedout areas, pixellation, etc, and
greatly improve the overall image quality.
So it stands to figure that you can possibly add some random noise
to a waveform that has some non-random interference on it, and
effectively "mask" that interference. I have actually thought
about trying this in the past. Might actually work for small
"nibby" noise, and leave the longer-term waveforms being captured
more or less intact.
Cheers and thanks for the input,
