May be I'm slow today...but that paragraph is really unclear to me, and I
know this stuff quite well.  What exactly do you mean by 'for a given
sensitivity from the analog circuitry'?  Sensitivity  can describe one of
many characteristics, so this seems ambiguous.

Also, what do you mean by 'to the density ranges that the analog circuitry
resolves'.  The above paragraph seems to intermix (confuse) different
concepts/terms, and really comes across, at least to me, as not very
comprehdable.  I don't think 'resolves' is the right word there.

Also, 'analog values that the CCD *does* resolve'?  Again, resolve doesn't
really sound right here...  The only thing in the described system that is
'resolved' is the A/D.
