1、北京邮电大学信息与通信工程学院电路综合实验报告串行口数据传输的仿真及硬件实现姓名：学号：班内序号：班级：指导老师：日期：2014年10月10日摘要：本实验模拟了现代数字逻辑电路中的数据传输过程。使用连续的代表0、1的高低电平作为数字信号，将该数字信号从输出端发送到接收端，并分别用串行、并行两种方式进行锁存，检测。本实验模拟了序列信号的发生装置、串并转换装置、串行并行两种方式的检测装置、锁存输出和控制电路，实现了一个简单的串行口数据传输模型。在此试验中，通过对常见芯片的组合实现功能，将一串由0、1组成的数字信号进行传输、转换、检测，使之显示在数码管上成为可读信息。并且，还

2、实现了对此电路显示的控制，使数码管在满足条件的情况下才点亮。在实验中，还使用了QuartusⅡ对设计的电路进行了仿真模拟。关键字：数据传输、串并转换、数据检测、QuartusIIAbstract：Thisexperimentsimulateddatatransferinmoderndigitallogiccircuit.Digitalsignalwastransferredfromtheoutputterminaltothereceivingend,whichwasconsistedofcontinuoushighorlowlevelrepresent0and1asdi
