摘　　要：带通采样定理是中频采样理论的基础,不同的文献中对带通采样定理有不同的论述形式。首先对一种表述较全面、准确的带通采样定理进行分析,然后利用分析结果对在雷达、通信等数字信号处理中广泛使用的传统的中频采样理论进行改进与完善,从而使正交检测器的工程实现具有更大的灵活性,可以满足不同情况的要求。There are many different expressions about bandwidth sampling theorem available in different references. In this paper,analysis of one typical bandwidth sampling theorem is made first followed by modification to the traditional IF sampling theorem by means of the analysis results. In this way, the engineering implementation of the quadrature sampling detector can be more flexible and meet different occasions.
