WebMar 11, 2013 · This CIC filter is a second order filter and 4-times downsampler. The filter attenuates frequencies above the new (lower) Nyquist frequency by about 25 db (factor of 17). The effective passband is about 0.4 of the new Nyquist frequency. The filter takes 100 cycles when it is only integrating, but 190 cycles when it is doing the downsampling and ...
WebJun 10, 2016 · The higher order the sinc filter, the longer it will take to settle – but with the bonus of better stop-band attenuation. Figure 2 shows how the sinc 1, sinc 3 and sinc 5 filters respond to a unit step input. Note that the order of the sinc filter matches the number of samples it takes to settle to the input. WebThe FPGA performs the pre-processing stage proposed by Hegde [29], composed of a CIC filter and two half-band filters in order to downscale the sample rate, followed by a low-pass FIR filter to ...
WebJan 14, 2005 · The CIC filter It is easy to understand the CIC filter in the frequency domain. As shown in Figure 1, the CIC filter is a cascade of digital integrators followed by a … WebThe order and decimation ratio of CIC filter was shown in simulation results. This proposed work has high performance and low complexity compared to existing methods [4], [1] and [2].The future plan of this work is to design a five stage CIC filter using hardware language and implemented in FPGA.
WebOct 3, 2016 · Signal decimation using a compensated CIC filter. Decimation is the process of converting a time-domain signal sampled at frequency fs f s into a signal sampled at frequency fs/R f s / R, where R R is the decimation rate. Downsampling alone, i.e. keeping one sample every R R samples is not sufficient. A low-pass filtering step must …
