一、设计任务：
设计一个具有锁存与显示功能的8人抢答逻辑电路。抢答开始之前，由主持人按下复位开关清除信号，所有的数码管均熄灭。当主持人宣布“开始抢答”后，计时器开始计时并以数码管显示，在规定的时间内首先做出判断的参赛者立即按下按钮，数码管显示该选手的序号，而其余七个参赛者的按钮将不起作用，信号也不再被输出，直到主持人再次清除信号为止。
二、设计要求：
1. 抢答器同时供8名选手或8个代表队比赛，分别用8个按钮S1 ~ S8表示；
2. 设置一个系统清除和抢答控制开关S，该开关由主持人控制；
3. 抢答器具有锁存与显示功能；
4. 抢答器具有定时抢答功能，且一次抢答的时间由主持人设定（如30秒）；
5. 参赛选手在设定的时间内进行抢答，抢答有效，定时器停止工作，显示器上显示选手的编号和抢答的时间，并保持到主持人将系统清除为止。
三、设计报告要求
1. 写明设计题目、设计任务、设计目的；
2. 详细阐述方案论证过程；
3. 详细阐述设计过程，包括系统框图、各部分功能电路图，并给出相关原理说明；
4. 列出所用元器件；
5. 写出设计体会与建议。
提示：
1. 系统设计可分为四个模块：
（1）设计抢答器电路。 （2）设计可预置时间的定时电路。
（3）设计报警电路。 （4）设计时序控制电路。
2. 设计过程中可能需用到的集成电路有74LS148、74LS279、74LS48、74LS192或74LS161、555等，请同学们查询相关集成电路的资料。
