Sigma-Delta Digital Converter Suitable for a Resistive Displacement Sensor With a Floating Slide.

A sigma-delta-type digital converter (SDC) suitable for a resistive-potentiometer-type displacement sensor with a floating slide is presented here. The delta modulator in a conventional SDC is suitably altered to incorporate, as its integral part, a resistive-potentiometer-type displacement sensor with a floating slide. The operation of the 1-b quantizer in the SDC is modified such that the digita...
