数字钟是一种用数字电路技术实现时、分、秒计时的装置，与机械式时钟相比具有更高的准确性和直观性，且无机械装置，具有更更长的使用寿命，因此得到了广泛的使用。数字钟从原理上讲是一种典型的数字电路，其中包括了组合逻辑电路和时序电路。目前，数字钟的功能越来越强，并且有多种专门的大规模集成电路可供选择-Digital Clock is a digital circuit technology with the hours, minutes, seconds, timing devices, as compared with the mechanical clock has a higher accuracy and intuitive, and no mechanical devices, with more longer life, so be a wide range of use. Digital clock from the principle of speaking, is a typical digital circuits, including combinational logic circuits and sequential circuits. At present, the digital clock and more powerful, and there are a variety of specialized large scale integrated circuits to choose from
