Say you have multiple circuits running off one battery (+12v).
Say the output of circuit #1 oscillates about +1.5v amplitude of 1v. (+1v - +2v)
I can't modify circuit #1. But I want to press a button, and while that button
is pressed down, offset the output of circuit #1 by +1.5v. (+2.5v...

The ECU sends a +5v reference to the sensor. The sensor then returns
a +.2v to +4v signal...
