A simple design for wideband compensation of a cascaded-integrator-
comb (CIC) decimation filter is presented. The proposed multiplierless
linear phase finite impulse response compensator works at a low
sampling rate and requires only three additions/subtractions. The struc-
ture of the filter is independent of the decimation factor and the number
of the cascaded CIC filters K. However, the proposed filter requires K
or K 2 1 stages, depending on the parameter K of the CIC filter.
