It can also be viewed as a special (degenerate) case of a downward expander.

"Gating" is the term I'd probably use, but I come from an audio
background.

In Mathematica it is called "Chop". It is mainly used to get rid of 
round-off errors.

In Ohio it's called "putting the kabosh" on the small numbers.

"Dead zone", maybe?

There is something here:

https://en.wikipedia.org/wiki/Deadband

The question is how to come out of
the "dead zone", by jumping to the
correct value or ramping up to it.

^^Those.   Another that is sometimes used is "sensitivity threshold".

In audio, that is called a noise gate.

In radio receivers, that is called a squelch.

Clipping is when you set a strong amplitude to some fixed limit.
But what about the other end - when it is small, and those tiny
amplitudes are replaced by zero?
