- 设计一个可容纳四组参赛的数字式抢答器,每组设一个按钮供抢答使用。抢答器具有第一信号鉴别和锁存功能,使除第一抢答者外的按钮不起作用;设置一个主持人“复位”按钮,主持人复位后,开始抢答,第一信号鉴别锁存电路得到信号后,用指示灯显示抢答组别,扬声器发出2—3s的音响。 设置犯规电路,对提前抢答和超时答题(例如3min)的组别鸣笛示警,并由组别显示电路显示出犯规组别。 设置一个计分电路,每组开始预置10分,由主持人记分,答对一次加1分,答错一次减1分。 -a design can acc

用VHDL语言实现四人智力竞赛抢答器的设计
- 1、用feng模块将选手按下按键信号输出高电平给锁存模块lockb,进行锁存的同时发出aim信号实现声音提示,并使count模块进行答题时间的倒计时,在计满100妙后送出声音提示; 2、用ch41a模块将抢答结果转换为二进制数; 3、用sel模块产生数码管片选信号; 4、用ch42a模块将对应数码管片选信号,送出需要的显示信号; 5、用七段译码器dispa模块进行译码。

- 三路智力竞赛抢答器,利用VHDL设计抢答器的各个模块,并使用EDA 工具对各模块进行仿真验证。智力竞赛抢答器的设计分为四个模块:鉴别锁存模块;答题计时模块;抢答计分模块以及扫描显示模块。把各个模块整合后,通过电路的输入输出对应关系连接起来。设计成一个有如下功能的抢答器: (1)具有第一抢答信号的鉴别锁存功能。在主持人发出抢答指令后,若有参赛者按抢答器按钮,则该组指示灯亮,数码管显示出抢答者的组别。同时电路处于自锁状态,使其他组的抢答器按钮不起作用。 (2)具有计分功能。在初始状态时,主持
