A digital measurement input for an electric automation device has a receiving device configured to receive digital input measurement values generated by sampling an analog measurement signal at a first sampling rate, and a signal converting device configured to generate digital output measurement values from the digital input measurement values and to provide digital output measurement values. The sampling rate and sampling times of each digital output measurement value is adapted to a specified sampling rate and/or specified sampling time. The signal converting device has a digital encoder filter on the input side and a digital decoder filter on the output side, between which an interpolator is provided. The encoder filter, the interpolator, and the decoder filter are matched to one another so as to adapt the sampling rate and/or sampling time of the digital input measurement values. |
