摘　　要：数字电视信号的调制是用载波信号的某些离散状态来表征所传送的信息,在接收端只对载波信号的离散调制参量进行检测.以VSB调制为线索,着重介绍了数字电视(HDTV)系统中8-VSB的调制原理、频谱特性和硬件实现方法,并说明了其数据帧结构及传输特点.Digital TV signal modulation is a message transmitting method which is expressed by some discrete states in carrier wave.Only carrier wave modulating parameter is detected .According to the vestigial side band(VSB) modulating principle, 8-level VSB modulating principle,hardware's realization,data vertical structure and transfer feature are emphatically introduced in the high definition television(HDTV).
