1. A method for performing analog-to-information conversion for multi-band signals, the method comprising:
receiving an input multi-band signal at M analog sampling filters;
sampling and down-converting N samples of the input multi-band signal at selected N analog sampling filters of the M analog sampling filters, where N is less than M;
digitizing the N samples of the input multi-band signal to produce N digital samples of the input multi-band signal;
multiplexing the N digital samples of the input multi-band signal into M digital samples of the input multi-band signal;
up-converting and filtering the M digital samples of the input multi-band signal at M digital reconstruction filters to produce a digital multi-band signal; and
processing the digital multi-band signal at a processing unit to obtain information contained in the digital multi-band signal.
