Time-to-Digital-Converter (TDC) sind elekt … Time-to-Digital-Converter (TDC) sind elektronische Baugruppen, die kurze Zeitintervalle messen und in eine digitale Ausgabe umwandeln. Streng genommen fallen darunter auch einfache Frequenzzähler. Es ist jedoch üblich, nur dann von einem TDC zu sprechen, wenn die Zeitauflösung besser ist als sich direkt mit Zählern erreichen lässt. Derzeit ist dies ab einer Auflösung von etwa 1 ns der Fall.ab einer Auflösung von etwa 1 ns der Fall.
, Il Time to digital converter (letteralment … Il Time to digital converter (letteralmente "convertitore tempo-digitale"), generalmente abbreviato in TDC, è uno strumento di misura digitale elettronico utilizzato per misurare intervalli temporali ad alta precisione che intercorrono tra eventi di varia natura. I TDC sono generalmente implementati all'interno di ASIC oppure programmati in un firmware per FPGA. La scelta di rendere digitale una parte o la totalità dei sistemi di misurazione elettronici è dettata dall’intento di sfruttare i ben noti vantaggi offerti da questa opzione; questo, unito alla facilità d'integrazione, sono le principali differenze rispetto al , altro metodo di misura del tempo. Vista la diversa natura degli eventi misurati, vengono solitamente utilizzati dei trasduttori che si occupano di convertire il relativo fenomeno fisico in segnale elettrico utilizzabile direttamente dal TDC, come diodo fotorivelatore a singolo fotone (SPAD), (SNSPD), Silicon Photomultiplier (SiPM), (CDL). Molti sono i campi in cui il TDC viene utilizzato, ad esempio applicazioni basate sulla misura del tempo di volo (e.g. LIDAR, , Spettrometria di massa a tempo di volo) oppure applicazioni basate sulla misura del tempo di decadimento di particelle (e.g. , (TCSPC).decadimento di particelle (e.g. , (TCSPC).

, In electronic instrumentation and signal p … In electronic instrumentation and signal processing, a time-to-digital converter (TDC) is a device for recognizing events and providing a digital representation of the time they occurred. For example, a TDC might output the time of arrival for each incoming pulse. Some applications wish to measure the time interval between two events rather than some notion of an absolute time. In electronics time-to-digital converters (TDCs) or time digitizers are devices commonly used to measure a time interval and convert it into digital (binary) output. In some cases TDCs are also called time counters (TCs). TDCs are used to determine the time interval between two signal pulses (known as start and stop pulse). Measurement is started and stopped when the rising or falling edge of a signal pulse crosses a set threshold. This pattern is seen in many physical experiments, like time-of-flight and lifetime measurements in atomic and high energy physics, experiments that involve laser ranging and electronic research involving the testing of integrated circuits and high-speed data transfer.ted circuits and high-speed data transfer.
