| Abstract: | The digital clock is made up of with different forms of counter as the base unit and it's very useful in many fields.Had timing and counting been existence,the principle and structure of the digital clock are used.Simultaneously,it's popular with consumers for it's smart,low price,high precision,and also for it's convenience,widely used in many fields and it's simply integrationization in everyday life. |
