Abstract
Analog AC to digital signal converter includes a sampling circuit which cyclically samples the analog AC signal to form analog sampling values, and an analog-digital converter for converting the analog sampling values to digital sampling values. A sign integrator integrates the sign of the digital sampling values, and a compensating voltage generator generates a compensating voltage in dependence upon the integration result. A combination circuit combines the compensating voltage with the analog sampling value from the sampling means and applies the combination result to the analog-digital converter. The circuit compensates any DC voltage component contained in the analog AC signal and avoids interferences resulting from such DC voltage component.
