Abstract
Algorithms have been studied using Monte Carlo techniques and implemented in a fast Xilinx Virtex II pro field programmable gate array (FPGA), in order to calculate and remove, after pedestal subtraction, the common mode of a group of adjacent channels. The implementation of the algorithms has been optimized both for speed and minimal FPGA resources, so as to be used in multi-channel applications. The aim of this work is to define the optimum algorithm for common mode calculation to be implemented for common mode rejection in the CMS Preshower detector.Keywords
