FPGA implementation of digital filters for nuclear detectors

Innovative filtering structures have been implemented on Field Programmable Gate Arrays (FPGA) for processing signals generated in nuclear particle detectors. These digital filters will contribute to develop new triggerless data acquisition systems. In this paper, we describe the structures of these filters and compare their hardware-implemented performances with the results of software simulations Particular attention has been paid to the consumption of FPGA internal components and to the maximum work frequency.
