此次设计与制做数字钟就是为了了解数字钟的原理，从而学会制作数字钟.而且通过数字钟的制作进一步的了解各种在制作中用到的中小规模集成电路的作用及实用方法.且由于数字钟包括组合逻辑电路和时叙电路.通过它可以进一步学习与掌握各种组合逻辑电路与时序电路的原理与使用方法.-Design and production of the digital clock digital clock in order to understand the principle, so learn to create digital clock. But also through the production of digital clock further understanding of the production of integrated circuits used in the role of small and medium-sized and practical methods. And As the digital clock including the combinational logic circuit and the circuit when Syria. through its further study and master the various combinations of logic circuits and sequential circuits Principle and usage.
