Prototype digital correlator for AMiBA
A wideband digital correlator utilizing high-speed Analog-to-Digital Converters (ADCs) and Field Programmable Gate Arrays (FPGAs) was developed for the Array for Microwave Background Anisotropy (AMiBA). The objective is to detect spectral lines for intensity mapping for cosmology study. A prototype one-baseline correlator using 5 Gsps ADC modules has been deployed for testing.
