EWB做的多功能数字钟
由振荡器输出稳定的高频脉冲信号作为时间基准，经分频器输出标准的秒脉冲，秒计数器满60向分计数器进位，分计数器满60向小时计数器进位，小时计数器按“12翻1”规律计数，计数器经译码器送到显示器；计数出现误差可用校时电路进行校时、校分、校秒，
可发挥部分：使闹钟具有可整点报时与定时闹钟的功能。
-EWB done by the multi-function digital clock oscillator output stable high frequency pulse signal as a time reference. Frequency Divider output by the standards of seconds pulse, aged 60 seconds to counter-counter rounding, Counter-to-60-hour counter rounding, by the Counter-hour "12 over a" law count, Counter by the decoder to display; Counting errors school circuit can be used for schools, school hours, school seconds to play : The alarm clock can be made with whole point regular alarm clock and timer functions.
