摘　　要：为将某一幅度的核辐射探测器模拟脉冲信号转为数字逻辑信号以供后续电路记录和处理,本文在研究普通单道脉冲幅度分析器电路的时序逻辑的基础上,利用较少集成芯片设计了一种新型的单道脉冲幅度分析器电路,并且进行了电路实验验证。实际实验结果表明,该电路不仅可以实现单道脉冲幅度分析器的功能,且能够在输入正弦脉冲信号频率达1.1 MHz时正常工作。A certain extent analog pulse signal of the nuclear radiation detector is converted into digital logic sig- nal for being recorded and processed in subsequent circuits. Based on studying the temporal logic of the tradi- tional single channel analyzer, a novel single analyzer circuit is designed using a few integration chips and veri- fied by testing. The actual experiment results show that the single channel analyzer circuit can not only realize the function of the single channel analyzer but also work steadily in the case of the input sine pulse signal fre- quency reaching 1.1 MHz.
