Abstract: A time interval measuring system is disclosed. In one embodiment, the time interval measuring system includes a plurality of time interval analyzers, each having a resolution that differs from a resolution of at least one other time interval analyzer in the plurality of time interval analyzers. The plurality of time interval analyzers are configured to receive a first event signal representing a first event, receive a second event signal representing a second event, and generate digital first estimates representing a time difference between the first event and the second event. The time interval measuring system further includes a post-processing unit configured to receive the digital first estimates and combine the digital first estimates according to at least one algorithm to generate a digital second estimate representing the time difference between the first event and the second event having higher precision than each of the digital first estimates.
