摘要
本文分析了以模拟电路为主的核仪表中.统计涨落对控制系统的不良影响。并重点介绍了在电路中增加一个由集成运放组成的迟滞比较器后,可对提高控制系统的可靠性、消除多种干扰信号等有较好效果。
In this paper,we will analyse the negative effect of statistical fluctuation in analogue circuit gauge. Fluctuation can make the control operation unreliable. A lagged-demand comparator may be mainly recomended. If this comparator was added to the circuit, the reliabity of control operation can be improved. Mean while, the usage of this comparator can eliminate many interference signals.
