Didn't the term "pre-distortion" originate in the astronomy world where
one creates an artificial star with a powerful laser, and then distorts
the telescope mirror in real time to minimize atmospheric effects
[twinkling]? That also reduces the twinkle on real nearby stars too.
Maybe that's something else. Pre-emphasis/De-emphasis in FM broadcast
[and analog land mobile FM] is sort of pre-distortion too.

Who ever coined the term "predistortion" should be taken behind the bicycle
shed and introduced to a 2x4. The terminology is the epitome of obfuscation!
