ABSTRACT:
The present invention relates to a measurement circuit for providing the digital value of an analog electrical signal. The digital measurement circuit for measuring an analog electrical signal produces a measurement signal (M) and includes an amplifier (1) which receives said electrical signal (I), followed by an analog-to-digital converter (2) which delivers digital data (N). The gain of the amplifier (1) is controlled by a control signal (C) and said gain can take up at least two values. The measurement circuit further includes a control unit (3) producing said control signal (C) and storing the digital data corresponding to different gain values, and includes means for producing the measurement signal (M) on the basis of said digital data (N).
