| Nov 10, 2018 at 13:11 | comment | added | Marcus Müller | @PeterSmith my 100 points bounty expires in 1 day; so rather write something quick and dirty and get those 100 points :) | |

| Nov 8, 2018 at 16:54 | comment | added | Marcus Müller | @PeterSmith ping? | |
| Nov 4, 2018 at 18:12 | comment | added | Peter Smith | Agreed; but it is an interesting phenomenon. More tomorrow. | |
| Nov 4, 2018 at 17:58 | comment | added | Marcus Müller | well, sadly it's probably correlated to the value observed, so you can't just say "hey, that's the sum of two independent zero-mean random variables, let's just add their variances to get the sum's variance". | |
| Nov 4, 2018 at 17:13 | comment | added | Peter Smith | I will take a stab at this when I have some time; consider however, that the difference between ENOB and the ideal resolution appears as (usually) a gaussian distribution. | |
| Nov 4, 2018 at 16:10 | comment | added | Marcus Müller | that's an implementation detail that I couldn't take into consideration here, since the fact that ENOB < nominal bits depends on imperfections with characteristics that strongly depend on the ADC architecture. An analysis of that would definitely extend beyond the scope of this answer – but if you have any insight, I'd be thankful! | |
| Nov 4, 2018 at 16:04 | comment | added | Peter Smith | One might intuitively think that ADC ENOB might play a role in this. | |
