WebComb filter (CIC) are commonly used as decimators for the sigma delta modulators. This paper presents the VLSI implementation, analysis and design of high speed CIC filters … WebA CIC filter is a special class of linear phase, finite impulse response (FIR) filter. CIC filters do not require multipliers and use a limited amount of storage. ... Using the maximum bit width for each integrator or comb section guarantees that no overflow occurs at the output of the filter. The maximum bit width also ensures that you obtain ...

This is a 5 stage decimating CIC filter … WebR, D, and N are the rate change factor, the differential delay, and the number of sections in the CIC filter, respectively. After decimation, the CIC response has the form: H c i c ( ω) = [ sin ( D ω 2) sin ( ω 2 R)] N. The normalized version of this last response is the one that the CIC compensator needs to compensate.
WebJan 11, 2016 · Problem is that a filter that should filter to a cutoff frequency of 0.01 Hz of an input bandwidth of 280 kHz/2 would be a $\frac{1}{14\,000}$-band filter; which is terrible, because it would be really really long if the transition width would have to be in the same order of magnitude; a hundred-thousand-tap filter isn't feasible for a lot of ...
