Abstract: A detector comprises an analog-to-digital converter. The analog-to-digital converter comprises an input for an analog receive signal and an output for a digital signal. The detector further comprises an edge detector. The edge detector comprises an input for a digital signal and an interface for an edge detection information. The edge detection information indicates the presence of an edge, if the digital signal indicates a change which is larger than or equal to a change threshold value.

Abstract: An analogue-to-digital converter comprises a window comparator. The window comparator comprises an input for an analogue input signal and an output for a comparison result indicating a result of a comparison of the analogue input signal with an upper bound and a lower bound of a level window. The analogue-to-digital converter further comprises a level window position signal generator. The level window position signal generator comprises an output for a level window position signal adjusting a position of the level window based on an information derived from the comparison result and indicating whether the level window should be increased, decreased or maintained. The analogue-to-digital converter further comprises an output for a digital information based on the comparison result.
