Interpolate signal using cascaded integrator-comb filter
DSP System Toolbox / Filtering / Multirate Filters
DSP System Toolbox HDL Support / Filtering
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 class of linear phase FIR filters that consist of a comb part and an integrator part.
The CIC Interpolation block requires a Fixed-Point Designer™ license.
