Recursive algorithms for real-time digital pulse shaping in pulse heig
ht measurements have been developed. The differentiated signal from th
e preamplifier (exponential pulse) is amplified and then digitized. Di
gital data are deconvolved so that the response of the high-pass netwo
rk is eliminated. The deconvolved pulse is processed by a time-invaria
nt digital filter which allows trapezoidal/triangular or cusp-like sha
pes to be synthesized. A prototype of a digital trapezoidal processor
was built which is capable of sampling and processing digital data in
real time at clock rates up to 50 MHz.
