A method for providing a high-resolution angle mark signal comprises the detection of a low-resolution angle mark signal and of a revolution trigger. Based on the low-resolution angle marks, angle marks are generated, subsequently, of a frequency that is increased by a multiplication factor, which can be preset. In order to achieve a precise multiplication of the crank angle signal even at highly dynamic speed changes, whereby with a high level of probability only a negligible deviation exists between the generated output marks and their theoretically correct positions, the high-resolution output angle marks generated since the occurrence of the revolution trigger are counted continually, and this counted value is compared, respectively, upon the incoming of a new input angle mark to the value that is calculated by counting the input angle marks since occurrence of the revolution trigger and multiplication by a multiplication factor, and the frequency of the output angle marks is corrected as of the new input angle mark as a function of this deviation.
Method for providing a high-resolution angle mark signal, and whereby a low-resolution angle mark signal as well as a revolution trigger are detected, and whereby the latter can also be synthesized from a gap in the low-resolution angle mark signal, and whereby, based on the low-resolution angle marks, angle marks are generated of a frequency that is increased by a multiplication factor that can be preset wherein the high-resolution output angle marks that are generated since occurrence of the revolution trigger are continually counted, and wherein this counted value is compared, respectively at the time of the incoming of a new input angle mark, to the value that is calculated by the counting of the input angle marks starting as of the occurrence of the revolution trigger and multiplication by a multiplication factor, and wherein the frequency of the output angle marks is corrected as of the new input angle mark as a function of this deviation.
