Currently, terrestrial-based astronomical observatories run by NOAO use analog data acquisition systems for reading charge coupled devices in telescopes. These analog electrical systems introduce a considerable amount of noise in the output signal. NOAO would like the team to create a digital data acquisition system and to implement the technique of over-sampling to filter any noise. Reduction of noise will improve image quality and reduce the time required to obtain high-quality images.
