| Abstract: | The bandpass sampling is a key technique to implement digital receiver. The center frequency and the bandwidth of the digital receiver will determine its sampling and processing methods. At first, the bandpass sampling theorem is discussed in detail in this paper, and then two types of bandpass sampling are presented to implement the digital receiver . |
