中频70M，30M带宽LFM信号，采样率为102.4M，数字下变频后，还进行了三倍抽取，最后还得到I，Q两路信号 -IF 70M, 30M bandwidth LFM signal, the sampling rate of 102.4M, digital down conversion, the samples were carried out three times, the last also I, Q two-way sig

基于宽带情况下数字下变频的全过程仿真程序 -Case based broadband digital down conversion of the whole process simulation program

信号带宽30MHz,输入采样率96MHz,输出采样率32MHz，抽取倍数为3的数字下变频DDC的Matlab仿真程序-Signal bandwidth of 30MHz, the input sample rate of 96MHz, the output sampling rate of 32MHz, extracted 3 times DDC DDC in the Matlab simulation program
