Patent ID: 8583390

Claim:
A method for digitizing an analog signal, comprising the steps of: separating the analog signal spanning a frequency range into a first signal occupying a first frequency band and a second signal occupying a second frequency band, at least a substantial portion of said second frequency band being higher than the first frequency band, the width of the first frequency band and the width of the second frequency band being different; digitizing the second signal with first digitizing elements having a frequency range less than the analog signal frequency range; digitizing the first signal with second digitizing elements; upsampling one or more of the first and second digitized signals; forming a digital representation of the analog signal from the upsampled digitized first signal, the upsampled digitized second signal, the digitized first signal, if the first signal has not been upsampled, and the digitized second signal if the second signal has not been upsampled, wherein the digital representation is a representation of the analog signal across substantially the entire frequency range of the analog signal, the digital representation having a bandwidth frequency content that has been digitized by the first and second digitizing elements, and where the bandwidth of a frequency content thereof exceeds a bandwidth of each of the first and second digitizing elements; and storing the digital representation in a computer readable medium.
