Abstract
Two edge detectors (12, 13) at the input (10.1) and the output (10.2) of a delay line (10) of the edge detector arrangement (11) generate detection signals of identical shape at the detected signal edges of a signal traveling over the delay line. The delay time of the delay line is selected so that the two detection signals partly overlap in time. A subtraction arrangement (16) generates, from the two detection signals, a difference signal that contains, in the overlap region, a zero crossing that can be detected by a zero crossing detector (17). At the time of this zero crossing, the zero crossing detector generates the switching edge of an edge detection signal that controls, for example, a signal switcher (9).
