Digital FIR Decimating Filter for GALFA Spectrometer Documented by Wonsop Sim, July 30th, 2004 Introduction: The GALFA Spectrometer Board requires a decimating FIR filter to reduce the bandwidth from 100MHz by a factor of fourteen to 7.14MHz. ... A filter with symmetric coefficients can reduce the number of multiplies in half by pre- adding input samples. ... The coefficients have been grouped so that they correspond to the fourteen pre- added input samples that are calculated in a filter section. ...
