Time-to-digital converter arrangement having a first and a second time-to-digital converters. The first one is configured to determine the existence or nonexistence of an event in a recurring first measurement window. The second one is configured to determine the existence or nonexistence of the event in a recurring second measurement window. A temporal relation of the second measurement window with respect to detecting the event is time-shifted by a first offset compared to a temporal relation of the first measurement window with respect to detecting the event.
