The digital instrument contains the input circuit for transforming a measured physical quantity into an analogue electric signal and an analogue-to-digital converter. Unique characteristics: It contains the interference generator (GZ) and the analogue adder (SA). At least one input of the latter is connected to the corresponding output of the input circuit (OW), while at least one of the remaining inputs is connected to the corresponding output of the interference generator (GZ). At least one of the outputs of the analogue adder (SA) is connected to the corresponding input of the analogue-to-digital converter (AC). |
