内容摘要
抢答器是为智力竞赛参赛者答题时进行抢答而设计的一种优先判决器电路,竞赛者可以分为若干组,抢答时各组对主持人提出的问题要在最短的时间内做出判断,并按下抢答按键回答问题。当第一个人按下按键后,则在显示器上显示该组的号码,对应的灯亮,同时电路将其他各组按键封锁,使其不起作用。因此要完成抢答器的逻辑功能,该电路应包括抢答器鉴别模块、抢答器计数模块、译码模块、计数模块。

Abstract
Responder is the answer for the quiz participants to answer in the design when a priority decision circuit, and the race can be divided into several groups, answer in each group on the host issues raised in the shortest possible time to make judgments , and press the answer in answer key. After pressing the button when the first person, then the display shows the number of the group, the corresponding lights, while other groups will be key circuit block, it does not work. If the answer in time, no answer in, the alarm lights. Answering questions, all the keys from the host to restore and re-start the next round of the Responder. So plete the answering device logic functions, the circuit should include Responder identification module, Responder counting module, alarm module, decoding module, frequency module.
KEY: Responder Identification Count
设计要求
,分别用4个按钮p0~p3表示。
,该开关由主持人控制。
。即选手按动按钮,锁存相应的编号,并在LED和数码管上显示,同时提示灯亮。选手抢答实行优先锁存,优先抢答选手的编号一直保持到主持人将系统清除为止。
二、方案设计与论证
概述
将该任务分成三个模块进行设计,
