摘要
详细阐述了一种以Sallen-Key滤波器为基础的新型数字高斯成形的方法。运用二阶微分方程建立高斯成形数学模型,在模型解算过程中利用数值微分算法得到一个通用的输入信号与输出信号的数值递推解,从而实现了核脉冲信号的数字高斯成形。通过标准指数信号的模拟以及实际测量信号的模拟,确定了数字高斯成形的参数。
A novel model of digital Gaussian filtering is presented in this paper based on Sallen-Key filter.Depending on a second-order differential equation,the authors obtained a general numerical recursive root between the input and the output by applying numerical differentiation algorithm,and implemented digital Gaussian filtering of nuclear pulse signal as well.The operator of the model is confirmed by standard index signal and actual measurement signal simulation.
