数字电子钟是一个对标准频率(1Hz)进行计数的计数电路。由振荡电路形成秒脉冲信号,秒脉冲信号输入计数器进行计数,并把累计结果以“时”、“分”、“秒”的数字显示出来。秒计数器电路计满60后触发分计数器电路,分计数器电路计满60后触发时计数器电路,当计满24小时后又开始下一轮的循环计数。由振荡电路、计数器、数码显示器、校时电路、整点报时电路等几部分组成。
Digital electronic clock is a count of the standard frequency (1Hz) count circuit. By the oscillation circuit to form a second pulse signal, the second pulse signal input counter to count, and the cumulative results to “hours ”, “minutes ”, “seconds ” figures displayed. Second counter circuit counts after the trigger sub-counter circuit 60, sub-counter circuit after the trigger counter circuit count 60, when the full 24 hours and then start the next round of cycle count. By the oscillation circuit, counter, digital display, school circuit, the whole point timekeeping circuit and other components.
