Paper Abstract

The gigabit digital filter prototype has been developed with the FPGA (FIeld Programmable Gate Array) for the radio astronomical observation. The digital filtering techniques enables a variety of observing modes defined on the data acquisition system, even with a fixed sampling frequency A/D converter. In this study, the principle of gigabit digital filter design is described in detail, parallel processing design of a FIR (Finite Inpulse Response) filter is presented, and the results of the test manufacturing are shown.
