资料介绍

为实现在时域中对核信号前置放大滤波电路进行数字分析,以常用的正相和反相放大滤波电路为研究对象,阐述一种建立放大滤波电路数字模型的方法。通过推导电路的微分方程,并采用微分方程数值解的方法,将求解微分方程解析解转换为求解微分方程数值递推解,从而建立电路的数字模型。通过对这两种电路的数字模型进行仿真,达到对正相和反相放大滤波电路进行数字分析的目的。通过将数字模型应用于实时核脉冲信号分析,为进一步采用FPGA技术将放大滤波电路进行数字硬件实现提供必要的理论基础。

A method of establishing a circuit numerical model has been proposed in this paper to analyze numerically nuclear signal preamplifier filter circuits in time domain based on inverting and noninverting amplifier filter circuits. The problem of how to solve specific analytical solutions for differential equations is converted to the problem of how to solve numerical recursive solutions by deriving the differential equations for circuit and by applying the numerical solution of differential equations. A numerical model for circuit is established accordingly. The numerical models of the two circuits mentioned above are analyzed numerically in time domain and their filtering characteristics re-recognized through sim...
