Abstract
For distinguishing two signals from different sources but with similar shapes, a signal generator offsets the signals from each other so that the values each signal assumes can be positively identified as being in permissible value ranges of one unique channel. The offset of the signals from each other is at least as large as the range of values for each channel. In this case, a mix up of channel from a signal generator to an electronic control unit can safely be detected. Also, if no positive assignment of a signal to one channel is possible, an error message can be provided. To carry out this analysis, not only the digital value of on and off of such a signal, but also the analog value, i.e. the absolute amplitude of that signal is measured for a determination of the offset. This can easily be done for two signals, but also for three or more, if only appropriate offsets are chosen.
