| Abstract: | Digital signal processing of bandpass signal is widely used in communications. With the development of digital signal processing,digital processing is desired to be implemented in RF, in which the features of digital signal processor (DSP) are the main problem. The techniques of undersampling of bandpass signal make the realization of IF and even RF digital signal processing possible. This paper summarizes the techniques of undersamping of bandpass signal and their applications. |
