JZD-1型和768数字测氡仪计数电路的分析和改进设计

ANALYSIS AND IMPROVEMENTS IN DESIGNING OF THE COUNTING CIRCUIT MODEL JZD-1 AND MODEL 768 DIGITAL INSTRUMENT MEASURING RADON IN GROUND WATER

摘要:

本文介绍了触发器跳变方程法^[1]在计数电路设计中的具体应用。在数字测氡仪研制过程中,我们应用这种方法对水氡仪研制初期的计数电路进行了分析,指出了存在的问题並进行了电路改进,设计了一种稳定、可靠而又简单的串行计数电路。

Abstract:

This paper presents concrete applying of equation of jumping of flip-flop in the design of the counting circuit. We apply the method in the analysis of counting circuit in the early days of the developing the instrument, improves the circuit and design a simple, stabilizing and reliable series counting circuit.
