摘　　要：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。The traditional method of processing intermediate-frequency signals is first analyzed. Then based on the narrowband signal sampling theory, a few kinds of structures which based on existed high speed digital components and capable of directly processing intermediate-frequency signals are given. Finally, a universal feasible scheme for intermediate-frequency sampling is presented.
