Abstract
The present invention relates to a method and a circuit arrangement for processing signals for an active motion sensor which generates at least one first sequence of input pulses that contain motion information. By at least one integrating filter circuit, each input pulse of a pulse train is integrated, and an associated output pulse is generated during a period in which the integrated signal is in excess of a predeterminable second threshold value after a predeterminable first threshold value has been exceeded so that the output pulse has a time delay with respect to the input pulse. As a result, noises of a duration which is shorter than the delay time are effectively suppressed.
