Abstract:
1. A transducer system, comprising: a transducer assembly, which operates based on changes of inductances between primary and secondary of a transformer to produce a differential signal that includes a noninverted partnoninverted signal and an inverted signal; a switch, that receives said noninverted signal and said inverted signal; and a processor, receiving an output of said switch, which produces both a first phase inversion signal for driving an input of said transducer assembly, and which selectively digitally creates an inverted transducer output, where said processor produces a square wave output as said phase inversion signal, and further comprising a filter which filters said square wave output to produce a substantially single frequency signal at a specified timing having a specified phase relationship relative to said first phase inversion signal based on instructions that are executed by the processor.
