Signal Inverter

This is an extremely simple utility chip.

To invert a directional signal you can just take a
(1) directional splitter and then put the + output of that into the - input of a (2) Directional Combiner, and then take the - output of the (1) Directional Splitter and punch that into the + input of the (2) Directional Combiner; essentially reversing the signs.

Presto!
