Hi
The gotcha is that all X7R tells you is that the temperature dependence of the
part
falls inside a certain set of limits. Back many decades ago there were very few
formulas
out there to make this or that spec part. Pretty much everybody made a part
type with
the same material.
Since the

Very good! I learned a bunch of things!
My suggestions for the earlier parts of the presentation:
- The discussion at the end of the "Types of Noise" slide should be
earlier, very near the beginning of the presentation. That is, start by
giving Context for why metrology has special requirements
Moin,
As some of you know, I have been allowed to give a tutorial on low noise
electronics
for this year's IFCS. As the whole conference has been turned into a virtual
one,
we were asked to record our tutorials and upload them. Additonally to the
conference
I decided to put my tutorial online
