The design method of a digital clock circuit is introduced. The quartz crystal oscillator and divider are used to generate a second clock signal,decode the counting results with dynamic scanning mode,and display the hour and minute and second on the common cathode LED digital tube in digital form. The circuit was realized with medium?scale pure hardware of CMOS integrated circuit. It overlays extensive contents and involves more knowledges. To enrol them in the independent experi?mental content can arouse the students' learning enthusiasm,improve the students' ability of engineering design,use various knowledge to analyze problems,and it has remarkable result to solve the actual problem.
