Measurement signal correction apparatus and method for correcting a measurement signal

摘要

A measurement signal correction apparatus includes an analog/digital converter, a correction factor providing unit, and a measurement signal correction unit. The analog/digital converter is configured to convert an analog measurement signal read in using an interface into a digital measurement signal using a reference frequency signal. The correction factor providing unit is configured to provide a correction factor determined on the basis of the reference frequency signal. The measurement signal correction unit is configured to multiply the digital measurement signal by the correction factor in order to obtain a corrected measurement signal.
