Abstract

The present invention relates to the determining of a sensor signal. For example, an enveloping waveform of the signal from a rotational angle sensor can be reconstructed for this purpose. To this end, a predefined number of successively sampled values of a signal from a rotational angle sensor are multiplied with the elements of a weighting vector. On the basis of a measurement vector weighted in this way, an enveloping waveform of a signal curve from a rotational angle sensor can then be determined and, therefrom, a phase angle can be calculated.
