These are the build notes for the nonlinearcircuits Chopper / Bi-directional module.
So what is it?
It's a eurorack format voltage controllable electronic switching module.

The bottom section is similar to your old fashioned gate controlled bi-directional router. Functionally, it behaves very much like the Serge triple bi-directional router, though the circuit is very different.
The top section is based on a 70's delta modulator, (at least in concept). Delta modulation (DM or Δ-modulation) is an technique of analog-to-digital and digital-to-analog signal conversion. It's used for information transmission where quality is not of primary importance.
The signals being switched are also sent through a comparator & they control the switching. Plus you can add CV to all of this. Cool !
