对传统中频信号处理进行分析,在窄带信号采样定理的基础上得出了利用现有的高速数字器件可以实现直接进行中频信号数字处理的几种结构,最后给出了在实际中可行的通用中频采样方案。
Based on the sampling theorem of narrow-band signal, several structures of digital IF signal processing can be achieved by using the existing high-speed digital devices. Finally, a general intermediate frequency Sampling program.
