Abstract: A time-to-digital converter (TDC, 110) obtains a Start signal to indicate the start of an event, and a Stop signal whose assertion indicates the stop of the event. The Stop signal can be asserted multiple times due to false indications of the event stop. The TDC continuously monitors the Stop signal to generate a separate digital value (T.j_i) for the duration from the event's starting time to each assertion of the Stop signal. The digital values can be analyzed to select the true duration of the event. Other features and embodiments are also provided.
