数字钟实验电路的设计与仿真

Experimental digital design and simulation of clock circuit

基于Multisim 10软件对数字钟电路进行设计和仿真。采用555定时器产生秒时钟信号,用时钟信号驱动计数电路进行计数,将计数结果进行译码,最终在LED数码管上以数字的形式显示时、分、秒时间。

The circuit of digital clock be designed and simulated based on Multisim 10.Using the 555 timer to generate a 1Hz clock signal.With the clock signal,drive counting circuit to count.Decoding the result of the count.The ultimate,display the hour numbers and minute numbers and seconds numbers on the LED digital tube in digital form.
