Abstract
Measurement amplification methods and devices for detecting the detuning of a measurement bridge () to which a bipolar, rectangular supply voltage (U) is supplied. The methods and devices use integrating A/D conversion and are characterized in that a reference voltage (U) used for the A/D conversion undergoes polarity changes synchronized with the polarity changes of the supply voltage (U). Offset and drift are eliminated by totaling an even number of individual measurements.
