Abstract This paper discussed the uniform under-sampling of multiple bandpass signals in digital receiver. For these multiple real or complex bandpass signals having arbitrary band position and bandwidth, the acceptable sampling rate has been given. Using this sampling rate to sample the input bandpass signal, an efficient data compression can be gotten. In the same time using band pass filter, these multiple bandpass signals can be transferred to the lower frequency. Finally, an example is given to show the correctness of the uniform sampling method of multiple bandpass signals.
