I agree. My first thought was two run the signal through a single sided log amplifier.
This would change the slew rates depending on the amplitude of the signal.

Agree with this also. On further consideration of the orginal posters drawing, I believe
that the signal is two triangle waves of different fundamental frequencies with a variable
PRT. I think it may sound like a ring modulated signal with the modulation signal
harmonicily related to the orginal signal. F modulating 2F maybe? Relatively easy to do
with my system.

Who knows - waiting for the orginal posters response.
