- 在超外差式接收机中，如果经过混频后得到的中频信号比原始信号的频率低，那么此种混频方式叫做下变频 （Down Converter or DC）。-In the superheterodyne receiver, if after mixing an intermediate frequency signal obtained by frequency lower than the original signal, then this method is called downconversion
qpskddc
- fpga实现dds和下变频。DDS 技术具有频率切换时间短，频率分辨率高，频率稳定度高，输出信号的频率和相位可以快速切换，输出相位可连续，并且在改变时能够保持相位的连续，很容易实现频率、相位和幅度的数字控制。它在相对带宽、频率转换时间、相位连续性、高分辨率以及集成化等一系列性能指标方面远远超过了传统频率合成技术。因此在现代电子系统及设备的频率源设计中，尤其在通信领域，直接数字频率合成器的应用越来越广泛。-fpga implementation dds and downconversion. DD
