1. A method for reconstructing an analog electrical signal, the method comprising:
- sampling a first analog electrical signal using a first sampling device and sampling a second analog electrical signal using a second sampling device, the first signal and the second signal being related according to a predefined function, the sampling of the first and second signals each occurring at predefined sampling rates;
at the first sampling device, generating a set of initial sampling values of the first signal, the set of initial sampling values including measured sampling values and further including missing sampling values corresponding to time segments in which no valid sampling values are generated;
calculating the missing sampling values of the first signal from sampling values of the second signal by taking into account the predefined function; and
outputting a reconstructed signal that includes the measured sampling values and the calculated missing sampling values.

Abstract
A method for reconstructing an electrical signal in which the signal and a second signal, which is related to the first signal according to a predefined function, are sampled at a predefined sampling rate. The occurrence of aliasing in a downstream digital low-pass filter may be substantially reduced if missing sampling values of the first signal are calculated from the sampling values of the second signal with the aid of the known function.
