摘要
利用计数器、译码器、门电路等中小规模集成电路和按钮开关实现比赛比分的记录、比赛时间和暂停时间的控制,用LED显示比赛时间、比分和暂停时间。
The aim of the design is to display the contest score, the start and pause time of the contest on LED, which will be controlled through the counter, the decoter, the medium-sized integrated circuits such as the gate circuits, and the button switch.
