摘要：

We present here the gigabit digital filter and the high-speed ADC (Analog-to-Digital Converter). Gigabit digital filters have been newly developed for the VERA (VLBI Exploration of Radio Astrometry) and the BEARS (SIS 25-BEam Array Receiver System). The 4-Gsps 2-bit ADCs were first made in the 2GC (2nd Generation Correlator) development for the ALMA (Atacama Large Millimeter / submillimeter Array). Finally, we propose new IF analog conversion and digital sampling processes, with the digital filter and high-speed ADC.
