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.
