数字钟电路的设计

Design of Multi-purpose Digital Clock Circuit

数字钟是一种采用数字电路实现对时、分、秒数字显示的计时装置。本文运用555定时器构成的多谐振荡器作为数字钟的时钟源设计了一种简单的数字钟电路,以实现电路对时间的显示。要求设计的数字电路不仅可实现计时功能还应具有一定的扩展功能。

Thedigital clock is a kind of timing apparatus which can show hourandsecond and minute with the digital circuit.A simple digital clock circuit is designed through a clock source which is a astable multivibrator which consists of a 555 timer.And so the time can be demonstrated.The digital circuitdesign not only has timing function,but also has some expansionfunctions.
