1. A method of sensing position based on information from a position sensor, comprising:
receiving said information from the position sensor, as the position sensor moves, as an electronically-sensed signal, said electronically-sensed signal being a differential signal that includes a noninverted signal part and an inverted signal part; using a processor for creating an inversion signal for the differential signal, by using said processor to produce a square wave output having a specified phase relationship relative to said differential signal, based on instructions that are executed by the processor; filtering said square wave output to produce a filtered signal at a specified timing as said inversion signal; using said filtered signal as a trigger to cause inversion of the differential signal to produce an output indicative of said position sensor. |
