CORRECTION OF COUNTING LOSSES OF THE PRELOADED FILTER PULSE PROCESSOR

By adapting noise filtering to individual pulse intervals, the Preload ed Filter (PLF) pulse processor (1) combines high resolution with opti mum throughput efficiency. As a consequence, its output pulse interval distribution contains strong non-random components which render conve ntional ADC dead-time correction an impossibility. Quantitative correc tion of dead-time and pileup losses of the PLF processor may be achiev ed. however, with the Virtual Pulse Generator(2), together with a new, distribution-independent method of measuring ADC losses which is base d on a pulse counting technique.
