Abstract
A method and apparatus for converting an analog waveform to a series of digital values includes receiving an input analog waveform to be digitized over a particular frequency band. A phase-sensitive frequency-domain representation of the input analog waveform is recorded. The phase-sensitive frequency-domain representation is read out and digitized to produce a spectral series of digital values. An output series of digital values that represent the analog waveform digitized over the particular frequency band is determined based on the spectral series. In some embodiments, the spectral series of digital values is produced with a conventional high dynamic range, low bandwidth digitizer that has a bandwidth at least a factor of two less than a width of the particular frequency band for digitizing the target analog waveform.
