Electronic circuit for correcting at least one digital measurement signal
Abstract:
An electronic circuit for correcting at least one digital measurement signal (ΣΔn, ΣΔ1, ΣΔ2) comprising at least one measurement channel having a sigma-delta modulator and a correction circuit. The sigma-delta modulator changes an analog measurement signal into a digital measurement signal in the form of a binary value sequence. The correction circuit corrects the digital measurement signal (ΣΔn, ΣΔ1, ΣΔ2) as a function of at least one correction datum (trim), wherein the correction circuit comprises at least one adding element and at least one multiplexer. The digital measurement signal is corrected in that the correction datum (trim) is weighted by means of the multiplexer and the adding element as a function of the digital measurement signal (ΣΔn, ΣΔ1, ΣΔ2).
