Abstract
Techniques for coupling with devices that convert displacements into differential voltages and improve the sensitivity of such devices. A transducer operates based on changes of inductances between primary and secondary of a transformer to produce a differential signal that includes a noninverted signal and an inverted signal. A switch receives the noninverted signal and the inverted signal. A processor creates a square wave signal for driving the transducer input, and also digitally creates an inverted transducer output. A filter operates to filter the square wave output from the processor to produce a substantially single frequency signal at a specified timing having a specified phase relationship relative to the first phase inversion signal based on instructions that are executed by the processor.
