设计制作一个可容纳4组参赛者的数字智力抢答器，每组设置一个抢答按键；

电路具有一第一抢答信号的鉴别和锁存的功能。在主持人将系统复位并发出抢答指令后，若参加者按抢答键，则该组指示灯亮并用组别显示抢答者的组别。此时，电路具有自锁功能，使别组的抢答开关不起作用。

设置计分电路。每组在开始时预置成6分，抢答后主持人计分，答对一次加1分。-The design can accommodate a the Entrants digital intellectual Responder, each set answer in a key　circuit has a first answer in the signal to identify and latch functions. Host to the system reset and sent the answer in instruction, participants answer in key, the group of the group light and display the answer in the group. At this point, the circuit has a self-locking function does not work in other groups to answer switch. Set Scoring circuit. Preset six points each at the beginning of the answer in scoring after the host, answer time, add 1 point.
