Hi Brad,
You are correct, I had a laps of memory that the person was using a Mac.
I do not believe the Mac version exists yet.

Todd,
My primary point was that with DyR defined as Dmax - Dmin, as it is by the
ISO, it is the range between the minimum discernable signal (which is what
the ISO calls Dmax) and the maximum signal before clipping (which is what
the ISO calls Dmin). Period.
But what do you mean when you say
Hi Todd,
This paper appears to speak to many of the issues discussed in
this thread:

I had a chance to look over that paper. The diagram you mention (I believe
you were referring to the sinusoidal wave +-5V signal...) that
alternatvely, if you just want to follow what is happening there concerning

Roy,
I can't figure out why you and Austin have such a mental block about
ranges and ratios.
And I can't figure out why you want to argue about this. Every reference
I've cited (and others have cited) agrees with me

... It is not hard to understand - 1dB is a small range (about 1.26 to 1),
100dB is a big range (100 to 1). The range we are discussing is the
range from MDS to max signal, which in scanner case is Dmax to Dmin.
There are _two_ ways to talk
There's a large number of ways you can write down numbers to define a
range. There is only one way in common use to express a range in a single
number that is independent of gain and other things that are irrelevant -
as a ratio.
You can express that ratio in a number of ways, dimensionless
To David and Austin
Austin replies to me:
Let me repeat, this paper says DyR is: if noise is present, the difference
between the loudest (maximum level) signal to the noise floor.
This is in contrast to Austin who says DyR is: (maximum signal level -
minimum signal level) / noise)

That is great news! Could we ask that you post a note here when it is
available. Thanks very much
