数字电子钟的分析与设计

The Analysis and Design of Digital Electronic Clocks

本系统采用小规模集成电路构成数字钟的硬件电路,由晶体振荡器产生脉冲,经过4060和D触发器进行分频,利用4518作为计时器,显示器采用共阴极七段数码管,配合显示译码器4511来显示计数器输出的数字。最后用电路仿真软件Electronics Workbench 8.0绘制出数字钟的完整电路图。对数字电路的学习起到了良好的辅助作用。

This system uses the small scale integrated circuits to construct digital clock＇s hardware circuit, and produces the pulse by the crystal oscillator, passes through 4060 and the D trigger carries on the frequency division, uses 4518 to take the timer, the monitor uses common cathode of the nixietube, coordinates to demonstrate that the decoder 4511 demonstrate the counter output the digit. Finally uses circuit simulation software Electronics Workbench 8.0 to draw up the digital clock＇s complete circuit diagram. To make the digital circuit＇s study in a good auxiliary function.
