摘　　要：带通采样技术是实现微字接收机的关键技术。数字接收机的载频和带宽影响其采样和处理的形式.本文首先较为详细地讨论了带通采样理论,然后在此基础上提出了两种采样形式的数字接收机的设计方案.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 .
