An 8 bits, 5 Giga samples per second Analog to Digital Printed Circuit Board has been designed by the authors for digitizing The Yuan Tseh Lee Array for Microwave Background Anisotropy and other radio telescopes.Abstract:
An 8 bits, 5 Giga samples per second Analog to Digital Printed Circuit Board has been designed by the authors for digitizing The Yuan Tseh Lee Array for Microwave Background Anisotropy(AMiBA) and other radio telescopes. Associated with the Field Programmable Gate Array platform developed by the Collaboration for Astronomy Signal Processing and Electronics Research community, AMiBA will have a digital correlator system in the future, that was fiscally difficult in 2001 when it was at design phase. The board can digitize input radio frequencies from DC up to 2.5GHz with a flatness of 5dB. The ENOB ranges from 6.1 to 6.5 bits across the 2.5GHz band, the SFDR from 41 dB to 48 dB, and the SINAD from 32 dB to 37.5 dB if the gain and offset tuning is applied.read more

TL;DR: Astropulse and Fly's Eye as discussed by the authors are two of the most popular SETI programs at IR, visible and radio wavelengths, which are orthogonal in search space; the Allen Telescope Array (ATA) “Fly's Eye” experiment observes a 100 square degree field by pointing each 6m ATA antenna in a di erent direction.
