Abstract

This document presents a performance assessment of digital filters applied to the signal arriving to the acquisition system of the Neutrinos-Angra Detector which is equipped with the PMT model R5912 by Hamamatsu. It is shown that the signal-to-noise ratio of the front-end output signal generated by single photoelectrons can be well enhanced, improving the detection efficiency for events of this kind. Some of the proposed filters will be designed to work as estimator of the peak amplitude value of the signal of interest. The considered filters will be described and the achieved results presented.
