Hi Julian,

Sorry to sound "snide", but er, DUH!  Do you know of a CCD that outputs
AC???  I don't!!!  It's ALL D/C measurements as it relates to scanners (and
actually, even audio).

I'll look over the rest of what you said when I get the time, but to answer
a question you raised, NO, I did NOT make up these terms, they are straight
from my reference material, though my references don't all use consistent
terms.  I have done nothing but try to CLARIFY them, since there seems to be
some confusion, and as I said, not everyone uses the same terms...so unless
we can agree on a set of terms, we really can't talk about this.

The start of this sounds positive...so you have raised my hopes ;-)

Regards,

Austin
