Abstract:
1. A method for digitizing an analog signal spanning a frequency range, comprising the steps of: digitizing a first portion of the analog signal spanning a first portion of the frequency range into a first signal occupying a first frequency band; translating a second portion of the analog signal spanning a second portion of the frequency range, at least a part of the second portion of the frequency range overlapping a part of the first portion of the frequency range, to a lower frequency band corresponding to a lower frequency portion of the frequency range; digitizing the translated second portion of the analog signal with digitizing elements having a frequency range less than the analog signal frequency range to form a digitized translated second signal; translating a third portion of the analog signal spanning a third portion of the frequency range, at least a part of the third portion of the frequency range overlapping a part of the second portion of the frequency range, to a lower frequency band corresponding to a lower frequency portion of the frequency range; digitizing the translated third portion of the analog signal with digitizing elements having a frequency range less than the analog signal frequency range to form a digitized translated third signal; forming a digital representation of the analog signal from the digitized first signal, the digitized translated second signal, and the digitized translated third signal, wherein the digital representation is a substantially accurate representation of the analog signal across substantially the entire frequency range of the analog signal; and storing the digital representation in a computer readable medium.
