    • Provided is a band pass sampling receiver which performs a sampling operation to a combined signal of RF signals of different frequency bands. The band pass sampling receiver performs the sampling operation by applying a sampling rate having a time lag to a combined signal of first and second RF signals of different frequency bands. And, by using a result of the sampling operation and first and second interpolant functions, the first and second RF signals are separated from each other. Herein, the first and second interpolant functions are determined based on the time lag, the sampling rate and frequency bands of the first and second RF signals.According to the band pass sampling receiver according to the embodiment of the present invention, the band pass sampling receiver selects the one frequency band among the plurality of frequency bands including the RF signals respectively by reconstituting of the signal process unit.
