数字下变频的Verilog程序，测试可以直接使用，将A/D信号下变频为基带I，Q两路信号-Digital down conversion of the Verilog program, testing can be used directly to A/D signal down-conversion to baseband I, Q signals two

通过VESA BIOS Extension(VBE)/Serial Control Interface(SCI)操作DDC读取显示器的EDID数据，或扩展硬件控制。-Read monitor EDID data from VESA BIOS Extension(VBE)/Serial Control Interface(SCI), or expand it for hardware control.

数字下变频在matlab中的仿真，实际测试好用，仿真结果不错，可以学习。-DDC in Matlab
