A method and a device process a motor signal of a direct current motor, in particular of an adjustment drive of a motor vehicle. The armature current and the motor voltage of the direct current motor are detected and used for determining the counter induction voltage of the direct current motor, by which a number of control signals having different ripple frequencies for controllable frequency filters are generated. The current ripples that are generated in a frequency dependent manner by the frequency filters, to which a filter input signal derived from the armature current and the motor voltage is applied, are synchronized with each other in the course of the ripple count. |
