【摘要】The design of multi-function quiz contest Responder can achieve 8 way to answer.The circuit consists of two parts:the main circuit and the extended circuit.The main circuit is composed of encoder,counter,latch and gate circuit.The expansion circuit consists of timers and necessary gate circuits.The host sets the answer in time according to the degree of difficulty of the problem,using the control button control system reset and responder,the countdown time and the number of answer players displayed on the display of decoding,the answer at the beginning and end of the alarm circuit to send out sound to remind the players and the audience.The circuit is simulated by Multisim
software,The
maximum
setting
functions
include
8
answer,answer time is 99 s,countdown display,player number display,Prompt start sound prompt,players answer the sound prompt and timing time to voice prompts and other functions.%设计的多功能智力竞赛抢答器可实现8路抢答;电路由两部分组成:主体电路和扩展电路;主体电路由编码器、计数器、锁存器和门电路组成,扩展电路由定时器和必要的门电路等组成;电路实现了主持人根据题目的难易程度设置抢答时间的长短,利用控制按键控制系统的清零和抢答开始,译码显示器上显示倒计时时间和抢答选手的编号,
抢答开始和结束时报警电路发出提示音以提示选手和观众;通过Multisim软件对电路进行仿真,可实现8路抢答、抢答时间的最大设置为99 s、倒计时显示、抢答选手编号显示、抢答开始声音提示、有选手抢答声音提示和定时时间到声音提示等功能.
