摘　　要：本文介绍了基于LabVIEW的核信号数字滤波器的设计与测试。该数字滤波器实现了3种核信号的数字滤波成形方法——基于小波分析技术的高斯滤波成形、匹配滤波成形和梯形滤波成形。为验证该滤波器的性能,利用计算机产生的数字化核脉冲信号作为信号源,对各种滤波成形算法的效果进行了测试。测试结果表明,该数字滤波器的性能良好,参数调节方便,适用于对核信号进行数字滤波成形。The design and test of a digital filter to nuclear signals based on LabVIEW were described .Three methods of digital shaping filter to nuclear signals ,which include Gaussian shape filtering based on wavelet analysis technology ,matched shape filtering , and trapezoidal shape filtering were achieved .To verify the performance of the filter ,a digital nuclear signal generator was designed as signal source .The test results of the effect of shaping filter algorithm were studied by altering the filtering parameter .The results show that the digital filter has good performance .
