Abstract: One embodiment of the present invention provides a signal-recording system. During operation, the system receives a plurality of radio frequency (RF) signals, separates the RF signals to obtain a first group of RF signals in a first RF band and a second group of RF signals in a second RF band, and simultaneously down-converts the first group of RF signals to a first group of low intermediate-frequency (low-IF) signals in a first IF band and the second group of RF signals to a second group of low-IF signals in a second IF band. The system further converts the first group of low-IF signals and the second group of low-IF signals to the digital domain, and simultaneously processes all of the converted low-IF signals.
