| Abstract: | The 8-VSB standard of Advanced Television Systems Committee (ATSC) is focused on and the architecture of system is discussed, then concrete implement of FPGA system are given. According to parameter of ATSC standard,analysis of ATSC standard is given. Based on the advanced weaver method, the scheme of the digital intermediate frequency which is changeable is put forward. Design of hardware-system process and the simulation results are given step by step. |
