An essential problem in this approach is to select a valid bandpass sampling frequency for the RF signals. Currently available methods for determining the valid bandpass sampling frequency ranges are either incomplete or computationally demanding. In this paper, we propose an efficient algorithm to find the complete ranges of valid bandpass sampling frequency for direct downconverting multiband RF signals. The computational advantage of the proposed algorithm over conventional methods is justified by computer simulation. The result can facilitate the design of multiband receivers for software defined radios.
