Abstract: A device receives a measurement signal, and assigns samples thereof to signal window formed from a portion of a sequence of the samples. During initialization, signal windows are determined as initialization windows, and therefrom noise windows are determined and analyzed using an Xth-order model. Initial coefficient tuples are assigned to each noise window, and noise tuples are ascertained therefrom. During examination, signal windows are determined as measurement windows, which use the Xth-order model. The associated coefficients that form a measurement tuple assigned to each of the measurement windows are ascertained, as is a distance of the associated measurement tuple from the noise tuple for each of the measurement windows. The measurement windows whose associated measurement tuple is at a respective distance from the noise tuple that is greater than a limit value are determined as error signal windows representing a signal error.
