Simple wideband CIC compensator
Gordana Jovanović Doleček · Electronics Letters · 2009
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 structure 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−1 stages, depending on the parameter K of the CIC filter.
