数字电子钟的设计，振荡器产生稳定的高频脉冲信号,作为数字钟的时间基准,然后经过分频器输出标准秒脉冲。秒计数器满60后向分计数器进位,分计数器满60后向小时计数器进位,小时计数器按照“24翻1”规律计数。计数器的输出分别经译码器送显示器显示。计时出现误差时,可以用校时电路校时、校分。-
Digital electronic clock design, stable high frequency oscillator generates a pulse signal as a digital clock time reference, and then passes through a divider output standard second pulse. Second counter at least 60 minutes after the binary counter, minute counter at least 60 hours after the binary counter, hour counter in accordance with the "24 turn a" regular count. The outputs of the counter is sent to the decoded display. Timing errors, you can use the circuit when the school when the school, school hours.
