Characteristics of the digital filter bank initially proposed for the
Second Generation Correlator (2GC) are summarized and we show that this
filterbank can be adapted to the Baseline ALMA Correlator design to
enhance the number of Field Programmable Gate Array (FPGA) resources,
power consumption and cost are given and we discuss implementation of
the digital filters in HardCopy devices to further improve performances
and cost.
