| 摘 要： | 设计了一种用分立元件构成的逻辑电平三态指示器，它能在三态输入(高电平、低电平、高阻)的条件下，有相应的三态指示(红灯亮、绿灯亮、灭灯)。集门电路、驱动电路和显示电路为一体．结构紧凑、逻辑严密、功能独特，是检测数字电路的有力助手。

| Abstract: | Tri-States indicator of logic level was designed by discrete component.It has three different display(the red lamp turning on,the green lamp turning on and both turning off)corresponding to the different three input(high level,low level and high impedance).It put the gate circuit,the drive circuit and the display circuit into one circuit with close frame,narrow logic and unique function,it is strong assistant of measure digital circuit. |
