Suppressing noise is important for the digital pulse processing (DPP) in the nuclear radiation detection, which requires precise knowledge of system noise. This work presents a DPP electrical module based on an FPGA of Lattice and derives a simple system noise distribution by experiment and analysis of acquired digital data using this system. The measured noise distribution of this system shows a multivariate Gaussian mixture model with different means and variances as a simple predict.
