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 ... WebA CIC filter consists of an equal number of stages of ideal integrator filters and comb filters. Its frequency response may be tuned by selecting the ... You can specify a digital FIR filter order L with the frequency response specified by vectors F (frequency) and A (magnitude response on break points F).

High Speed Polyphase CIC Decimation Filter - Dissonance
In digital signal processing, a cascaded integrator–comb (CIC) is an optimized class of finite impulse response (FIR) filter combined with an interpolator or decimator. A CIC filter consists of one or more integrator and comb filter pairs. In the case of a decimating CIC, the input signal is fed through one or more cascaded integrators, then a down-sampler, followed by one or more comb sections (equal in number to the number of integrators). An interpolating … http://www.ee.nmt.edu/~erives/531_14/CIC_filters.pdf WebA first-order CIC filter is made of an integrator and a Comb stage. A switch between these two stages performs the down sampling operation. To An overview of decimation filters, along with their operation and requirements.
