At the beginning of this discussion I was confusing "predistortion" with
"pre-emphasis" which in the FM broadcast field refers to the intentional
introduction of nonlinear audio frequency response of the transmission
chain, recovered by "de-emphasis" in the receivers. Now I understand
better what the discussion is all about.
