[time-nuts] Measuring short term stability minus linear drift

[Rick Karlquist]

I want to measure the short term stability of a source
with substantial linear drift.  I would like some measure
of stability along the lines of Allan deviation, but I
only want to measure the "noise" and ignore the "drift".
AFAIK, ADEV treats linear drift like a form of noise.
Has this problem been solved before?
Any ideas?
