System for collecting at least one signal simultaneously including an analog sampler (106), at least two digital frequency analyzers (DFAs) (108A-C) and a processor (110), the DFAs each coupled with the analog sampler, the processor coupled with each of the DFAs, the analog sampler for receiving the signal as at least one analog electrical signal, for folding the analog electrical signal using at least two different comb frequencies simultaneously into at least one sampled analog electrical signal and for demultiplexing the sampled analog electrical signal into at least two intermediate frequency (IF) signals according to the different comb frequencies, the DFAs for digitally sampling the IF signals into digital signals, the processor for determining a plurality of linear combinations of the IF signals with respect to the different comb frequencies used and for determining at least one frequency of the signal by evaluating the plurality of linear combinations of the IF signals. |
