Abstract For bandpass signal under digital quadrature sampling, there is spectrum shifting. Although the sampling frequency satisfies the sampling theorem, it may cause spectrum aliasing. The digital quadrature sampling theorem for bandpass signal is presented and the optimum design for the sampling system is also discussed in this paper.
