System simulation of digital pulse spectrometer

Benefiting from digitalization techniques, new-generation pulse spectrometers are characterized by better energy resolution, higher throughput, and improved stability and flexibility. MATLAB/SIMULINK, a platform for dynamic system simulation, was used to simulate such a digital pulse spectrometer. Each processing unit in the whole signal processing procedure was modeled with the relevant mathematical function and simulated with the abundant tools provided in SIMULINK. The simulation was implemented with sample input including noise, and the results verified that the system was all correctly simulated. The simulation system can be used to demonstrate the operating principles of a digital pulse spectrometer, to investigate key pulse processing algorithms, and as a computer-aided design tool for developing digital multi-channel analyzers (MCAs) or digital nuclear spectrometers.
