DECIMATION BY IRRATIONAL FACTOR USING CIC FILTER …

WebDescription. The CIC Interpolation block performs a sample rate increase (interpolation) on an input signal by an integer factor. Cascaded Integrator-Comb (CIC) filters are 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 first remington pump shotgun
