An improved apparatus for correcting electrical signals

摘要

A novel electrical circuit is disclosed that corrects for at least one undesired characteristic in an incoming electrical signal. In one embodiment, the apparatus reduces the number of wires heretofore required to correct electrical signals in a circuit. The apparatus also corrects for one or more of a second-order error in a measurement, an offset drift can be directly corrected during operation, and a span can be linearized during operation.
