Description: 我对一个输入调制信号：采样率FS=1200K，中心频率F0=300K，带宽300K。输入信号为一个[样点数,2]的矩阵,即I,Q两路.
进行频谱搬移，分为I，Q分量两路进行矢量乘法，NCO的设置为FC=300K，t=样点数乘以1/FS，
乘完以后我的频谱上显示竟然信号带宽增加了300K，但是中心频率没有改变，请问各位朋友是哪儿出了问题？谢谢您的阅读和意见-Digital Down Converter for matlab realized, certain design specifications that can be used to know VHDL Programming
