Patent ID: 7466767

Claim:
A method of increasing instantaneous bandwidth of a signal processing system comprising: splitting an analog input signal received by the signal processing system into a first set of signals, the input signal having a bandwidth; filtering and downconverting each of the first set of signals such that the entire bandwidth of the input signal is divided into portions and each of the first set of signals contains a corresponding portion of the bandwidth of the analog input signal; digitizing the first set of signals to form a second set of signals, each of the second set of signals containing the corresponding portion of the bandwidth of the analog input signal; filtering the second set of signals to form a third set of signals; and combining the third set of signals to form a processed digital version of the analog input signal having the bandwidth of the analog input signal, said combining comprising down-converting the third set of signals to a known frequency location, filtering the third set of signals to band limit their signal energies, selectively up-converting or down-converting each of the third set of signals to a respective frequency position and adding the signals in the third set signals together.
