Abstract
While combining AD converters that one is wide band but narrow dynamic range and the other is narrow band but wide dynamic range, it allows settings to provide a common intermediate frequency signal to the AD converters. A first BPFprovides a first AD converterwith the output signal obtained by getting an intermediate frequency signal Sif through a first band in the second Nyquist zone of the first AD converter. A second BPFprovides a second AD converterwith the output signal obtained by getting the intermediate frequency signal Sif through a second band in the third Nyquist zone of the second AD converter. At this time, the second band is set in the center portion of the second Nyquist zone band, and the first band is set in the center portion of the band of the intermediate frequency signal.
