WebThe interpolation filter used for the amplitude and phase path is derived from the basic cascaded integrator-comb (CIC) structure [80] with a few significant modifications. A … Webinverse of the CIC filter can be applied to achieve frequency response correction. Such filters are called “compensation filters.” For data rate down conversion, the compensation filter follows the CIC filter. For up sampling systems, the compensation FIR filter pre-conditions the data and is followed by a CIC filter. In other words, the
