Not a bad discussion, thanks.
A couple of nits. First, the correct definition of ENOB and full-scale
signal depends on whether the signal is unipolar or bipolar, i.e. whether
the DC is considered to be signal or merely an offset to keep the real (AC) >signal in range.
The definition used in the article is correct for AC-only signals like
radio, but 9 dB too low for AC+DC signals like photocurrents.
Second, AD is inconsistent in the way they quote data converter SNR—they >sometimes conveniently forget the factor of sqrt(12).

I am still happy with my 10 MHz Trio analog scope...
And my RTL_SDR sticks to about 1.5 GHz..
Anybody here use a 12 bit scope?

I can beat that. I have several 2 bit scopes. :-)
