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。 -1, using feng module will press a key player to a high signal output latch module lockb, issued at the same time to latch the signal aim to achieve prompt voice and answer module count of the countdown time, taking into account the post-Miao 100 sent the voice prompts 2, with the results of ch41a Answer module will convert the binary number 3, with sel digital control module chip select signal 4, with ch42a digital control module to the corresponding chip select signal, the display need to send signal 5, Seven-Segment Decoder with dispa decoding module.
