抽取:(接收端)
中频信号IF 20M(采样率是50M) 下变频信号 MIX_O 1M(50M) 采用CIC滤波器进行降采样率。
插值:(发送端)
基带信号上变频到1M，采样率是2.5M，采用CIC滤波器进行升采样率处理。
注释：升采样率或者降采样率不会改变原始信号的中心频率，但是频谱分布会发生改变。-Extraction: (receiver)
IF signal 20M (sampling rate is 50M) down-conversion signal MIX_O 1M (50M) using CIC filter down sampling rate.
Interpolation: (sending side)
Baseband signal up to 1M, the sampling rate is 2.5M, using CIC filter for sampling rate processing.
Note: The up-sampling rate or down-sampling rate does not change the center frequency of the original signal, but the spectral distribution will change.
