Abstract
A conversion system is disclosed for generating a desired bandpass waveform rom digital samples of a lower frequency, bandlimited original waveform. The system utilizes a single digital to analog converter and an impulse driver to generate a weighted pulse train that contains frequency shifted replicas of the primary spectra of the original waveform. Bandpass filtering rejects all but selected replica spectra for reconstitution.
