数字时钟是是一种现代化计数装置，它主要实现对“时”、“分”、“秒”进行数字显示的功能。该电路主要由脉冲发生模块、分频器模块，时、分、秒计数器模块、显示模块、校时模块、整点报时模块和倒计时模块组成。
该系统的工作原理为：将脉冲发生模块和分频器工作同作用下1Hz脉冲连接到秒模块的CLK端，使之工作，开始计时。其中分、秒模块均为60进制，时模块为24进制。再利用组合逻辑电路实现校时功能和整点报时功能。最后通过开关控制实现倒计时功能。

Digital clock is counted is a modern device, it mainly implements "time" and "minutes", "seconds" function of the digital display. The circuit mainly by the pulse module, the crossover module, hours, minutes, seconds counter module, display module, module, chime module, and countdown module.
How the system works as follows: pulse module and crossover work with under the 1Hz pulse CLK side connected to the second module to make it work, start the clock. Minute and second module is 60 binary and modules for 24 when the binary. Using combinational logic circuits to achieve error correction function and the chime function.Final countdown timer by turning the control.

Is a modern digital clock is counting device, it is mainly to achieve the "hour", "minute", "second" functional digital display. The circuit module, divider block, when mainly by the pulse, minutes, seconds counter module, display module, the school module, the whole point timekeeping module and countdown modules.
The system works as follows: The pulse generator module and dividers work under the same role 1Hz pulse CLK module is connected to the second end, to make it work, start timing. Where minutes and seconds are 60 binary module, the module is 24 hex. Re-use of combinational logic circuits to achieve school functions, and the whole point timekeeping function. Finally realized countdown function by switch control.

結果 (英文) 3:

digital clock is a kind of modern counting device, which is mainly of "when", "sub", "seconds" digital display function. The circuit consists of pulse generating module, frequency divider module, when, minutes and seconds, counter module, display module, timing module, the whole point timekeeping module and countdown module.
the working principle of the system is as follows: the pulse generating module and a frequency divider work connected to the second module of the CLK pulse 1Hz with the function, so as to make it work, start time. The minutes and seconds, module for the 60 band, when the module is 24 M. The combinational logic circuit implementation school function and the whole point timekeeping function.Finally achieve the countdown function by switch control.
