（1）抢答器可容纳四组选手，并为每组选手设置一个按钮供抢答者使用； 为主持人设置一个控制按钮，用来控制系统清零（组别显示数码管灭灯）和抢答开始。
（2）电路具有对第一抢答信号的锁存、鉴别和显示等功能。在主持人将系统复位并发出抢答指令后，提示抢答开始，计时显示器显示初始时间并开始倒计时，若参赛选手按下抢答按钮，则该组别的信号立即被锁存，并在组别显示器上显示该组别，同时扬声器也给出音响提示，此时，电路具备自锁功能，使其他抢答按钮不起作用。
（3）主持人对抢答结果进行确认，给出倒计时计数允许信号，开始回答问题，计时显示器从初始值开始以秒为单位倒计时，计数至0时，停止计数，扬声器发出超时报警信号，以中止继续回答问题；
（4）当主持人给出倒计时计数禁止信号时，扬声器停止鸣叫；
（5）参赛者在规定时间内回答完问题，主持人给出倒计时计数禁止信号，以免扬声器鸣叫，按下复位键，又可开始新一轮的抢答。
（6）初始状态每组5分，由主持人控制答对加1分打错减一分。当计分值发生变化时在数码管上显示出来。-( 1 ) Responder can accommodate four players , and players set for each group by using a button for the answer to set up a host of control buttons are used to control the system is cleared ( group display digital tube out the lights ) and Responder start .
( 2 ) peer latch circuit having a first answer signal , identification and display functions. After the host system reset and issued Responder command prompt answer in the beginning , time display shows the initial time and start the countdown , press the answer button if the players , then the signal is latched in the group immediately and display groups display the group , but also gives the speaker audio prompts , this time, the circuit with self-locking function , so that other answer button does not work .
( 3 ) the host to confirm the results of the answer given countdown count enable signal to start answering questions , time display from the initial value in seconds countdown, count to 0, stop counting , speaker-out alarm
