[PD] Simplification problem

[Andy Farnell]

I am trying to reduce a log waveform oscillator (as found with
a charging/discharging capacitor) to it's simplest form.

Note: It uses the soon to be deprecated form of [pow~] (with
reversed inlets)

Attached is the first attempt, and a slight improvement that
saves a couple of subtractions.

Any thoughts on reducing this further?

Also any ideas on constructing a proof that this has the
same spectrum as a triangle wave?

best to all,

Andy
