Przedstawiono budowę, zasadę działania i wyniki badań wielokanałowego modułowego licznika czasu. Umożliwia on równoczesny pomiar relacji czasowych pomiędzy impulsami wejściowymi (START), pochodzącymi z maksymalnie sześciu niezależnych źródeł zegarowych, a wspólnym dla wszystkich kanałów impulsem odniesienia (STOP). Moduły pomiarowe licznika wykonano z użyciem układów programowalnych FPGA Spartan-3...
One of the recent methods to increase the precision of time-to-digital (T/D) conversion is based on the use of multiple independent time coding lines (TCLs). The number and configuration of TCLs influence the resolution and precision of conversion. We considered and tested 14 different variants of such lines involving up to 16 TCLs. Obtained results indicate the optimal way of using independent coding...
