Recording of Coincidence Signals in a Software Medium

A virtual coincidence unit, a virtual counter and a virtual timer were developed via a software in this study. Different frequency signals supplied from a function generator were sent to a real coincidence unit. The same signals were transmitted to the virtual coincidence unit via a digitizer. Output signals of the real and virtual coincidence units were counted by real and the virtual counters. Count periods were set through real and virtual timers. For different count periods, coincidence counts obtained from the virtual counter were compared with those of the real one. It was seen that obtained results were highly compatible with each other for low frequency (25 – 55 Hz) signals.
