基于LabVIEW的脉冲幅度分析器仿真设计

Design of Pulse-height Analyzer Simulation Based on LabVIEW

基于核脉冲的随机性规律和脉冲幅度分析原理,设计了一个虚拟脉冲幅度分析器。在LabVIEW平台下实现了幅度为高斯分布的随机核脉冲信号的模拟产生,采用了双阈值算法对虚拟信号作寻峰处理,并将检测到的脉冲峰值作实时统计。整个设计旨在为实际的脉冲幅度分析提供功能参考和验证依据。从仿真运行结果来看,分析器能够在一定程度上模拟信号的随机性,达到对脉冲幅度的有效提取和简易统计分析的目的。

Based on the randomness of nuclear pulse in nuclear electronics and pulse height analysis principle,a virtual PHA is designed here with the LabVIEW.This design realizes generation of the simulated random nuclear pulses whose amplitude is in Gaussian distribution,used dual-threshold algorithm for peak searching,and the detected pulse peaks were finally for realtime statistics.This simulation is intended to provide function reference and verification for the real analysis.
