ABSTRACT:
A circuit configuration for metering pulse recognition includes an A/D converter that receives a signal containing metering pulses, and a digital comparator circuit for comparing the output signal from the A/D converter with a reference value. A detector unit evaluates the output signal from the comparator circuit. This means that an analog comparator can be dispensed with, and the chip area and the development complexity can be reduced.
