hi,
can anyone tell me much about s-curve bias? what is it? what does it
measure (if anything), what does it represent?
Thanks very much,
Depends on what you are talking about.
In analog electronics, an S-curve is the product of at least two
unequal but counteracting physical influences, organized to make use
of the relatively flat portion that can result, where one influence
may cancel out or temporarily reverse the influence the other.
It has the characteristic of potentially having a constant value at
three positions over a range of corresponding linear variables, and an
average value that has a fair tolerance over and slightly outside of
that range. This is a much larger range than could be maintained if a
a straight counteraction were attempted.
In some cases the intentionally reversing slope between the two
extreme calibration points can serve a distinct purpose in
discriminators.
