Gp. Westphal, CORRECTION OF COUNTING LOSSES OF THE PRELOADED FILTER PULSE PROCESSOR, Journal of radioanalytical and nuclear chemistry, 179(1), 1994, pp. 55-59
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.
