Verfahren und Anordnung zum Messen einer Meßgröße, insbesondere eines elektrischen Stromes, mit hoher Meßauflösung

摘要

In order to measure a measured value (I) in a predetermined measurement range (MR), a first measurement signal (M1), which is an unequivocal function of the measured quantity (I) in the measurement range (MR), and a second measurement signal (M2), which is a periodic and equivocal function of the measurement value (I) in the predetermined measurement range (I), are generated. A third unequivocal measurement signal (M3) in the measurement range (MR) which has at least the measurement resolution of the second measurement signal (M2) is derived from the two measurement signals (M1, M2).
