Study on the Method of Digital Signals Processing for Acquiring Nuclear Energy Spectrum

摘要: 介绍了将核辐射能量信号离散化后进行数字极零识别及补偿、基线扣除、低通滤波、脉冲成形和幅度分析等一系列数字化信号的处理方法,将长尾指数衰减信号成形为梯形波或三角波信号。用所述方法对实测波形进行离线处理后的结果表明,所获能谱的能量分辨率好于模拟式多道系统的测量结果。

Abstract: A method of digital nuclear radiation energy signals processing wasdeveloped. It includes polar--zero identifier and compensation, baseline subtraction, low-pass filter, pulse shaping and amplitude analyses. The method can convert a signal withlong exponential attenuating tail to a trapezoidal or triangular pulse. Processing the sig-nal in off-line, the preliminary experimental tests show the potential advantages of thesetechniques in high resolution spectroscopy.
