摘　　要：在核信号处理过程中,对前置放大器输出信号的滤波整形十分重要,它涉及到如何能实现最佳信噪比的传输问题。论文利用矩形小脉冲等效电荷灵敏前置放大器的输出信号,对其进行滤波整形,提出在整个滤波成形过程中的设计考虑,指出滤波成形电路在频域上的关键频段问题,利用NI MULTI-SIM软件仿真设计出一款滤波成形电路。In nuclear signal it relates to how to achieve processing , the filtering and shaping of preamplifier output signal is very important, the best signal to noise ratio of the transmission problem. The paper uses a small rectangular pulse equivalent charge sensitive preamplifier output signal, and the filtering and shaping of siganal is done. At same time, it presents considerations in the entire filtering and shaping process , and it points out that the filteing and ulated and designed shapingeircuit in the frequency domain key band problem. A filtering shaping circuit is sim- by using NI MU1TISIM software.
