ABSTRACT:
A detector receives energy pulses and a lossy integration circuit generates a lossy integration that, for each pulse, increases over the pulse duration to a maximum value and then decays. The lossy integration is sampled, with a sampling rate and decay rate such that the sample is within a given acceptable error of the maximum value. The sample represents the pulse total energy, within the given acceptable error. An optional circuit and processing function calculates a total accumulated energy over a plurality of pulses.
