WebThe script uses the frequency sampling method to design a FIR filter that has an inverse sinc frequency response. The overall system response is plotted for you to verify key system specifications such as the pass band ripple and stop band attenuation. ... A FIR filter follows the CIC filter to provide compensation to CIC filter frequency droop ... WebDetermine the ideal frequency response by sampling the normalized magnitude response of the CIC filter before inverting the response. Generally, only equalize the response in the passband, but you can sample further than the passband to fine tune the cascaded response of the filter chain. The CIC IP generates a MATLAB script

http://www.tsdconseil.fr/log/scriptscilab/cic/cic-en.pdf WebThe CIC and FIR filters convert in-phase and quadrature signals sample rate to 11.484 MHz while maintaining the input signals spectrum information. The decimation filters also reject out-of-band noise. Therefore, the output of this rate conversion system should be noiseless down sampled sinusoidal waves of frequency 4.57 MHz.

WebAn important parameter is the required frequency response. In particular, the steepness and complexity of the response curve is a deciding factor for the filter order and feasibility. A first-order recursive filter will only have a single frequency-dependent component. This means that the slope of the frequency response is limited to 6 dB per ... WebThe 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.
