摘　　要：文章对几种常见的核电子学滤波电路进行了数字模拟分析。利用拉普拉斯方法,得到了CR、R-C以及极零相消电路的输出函数,并通过Matlab模拟了负指数输入信号时的不同输出信号。在此基础上,模拟了低通S-K滤波成形电路的输出信号。结果表明,模拟得到输出信号与实际电路的输出信号具有相同的波形特性,该方法可以应用于核电子学滤波电路的分析。A new method of simulating filter circuits in nuclear electronics is proposed in this paper. The output functions of CR circuit,RC circuit and pole- zero cancellation circuit were obtained by using Laplace transform method. Different output signals of the circuits were simulated when the negative exponential signal is the input signal. Besides,the output signal of the low pass S- K filter was also discussed by using the new method. The simulating results indicate that the shape of output signals from the presented method is the same as the shape of the signals from the actual circuits,and the new method can be applied in the analysis of filter circuits in nuclear electronics.
