电子线路综合设计乒乓球比赛模拟及计分器设计2014年6月摘要在信息社会高速发展的今天，数字电路芯片已经实现高度集成化，并逐步渗透到医学、计算机等各个领域，对人类的生活有着深远的影响。

本设计采用基本门电路以及74LS系列芯片的搭建，以multisim 12.0软件为平台进行仿真，实现了对乒乓球游戏的模拟。

主要解决的问题有：（1）模拟乒乓球的轨迹：用双向移位4位寄存器74194以及基本门电路实现；（2）球速的调节：利用555电路实现；（3）球被击中、犯规的判断；（4）计数器的使用：采用74LS90和74LS161的组合，给玩家计分；（5）关于比分的显示：通过CD4511译码芯片将计数器的输出状态显示到2位共阴极数码管上。
