You have a black box. There are four wires protruding out of the box, we'll call them North, South, East, and West. If you apply 1 volt between the north and east terminals, the south and west terminals will show 1/4 volt output. If you apply 1 volt to the East and south terminals, the north and west terminals will output 1/4 volt. If you apply 1 volt to the South and west terminals, 1/4 volt will appear at the North and East terminals. Finally, if you apply one volt to the North and west terminals, 1/4 volt will appear at the south and east terminals. What is in the black box, and exactly how is it wired?
