Description: 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 accommodate four groups participating Digital Answering Machine, each with a button for Responder use. Responder is the first signal to identify and latch functions, in addition to those first Responder button ineffective; Moderator set up a "reset" button, reset moderator, began Responder, the first signal differential latch circuit signals to be used indicator shows Responder groups, loudspeakers issued 2-3s sound. Fouls circuit set to advance Responder and overtime to answer (for example, 3 min) groups warning whistle, with bands indicate foul show circuit group. Points set up a circuit, each started 10 minutes preset by the moderator points, a plus one correct answer, by a relaxation time points.
