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.
