I made some changes. I may do some more tweaking. Hope I'm not stepping on anybody's feet. TCMike 03:38, 27 December 2006 (UTC)
I changed the comparison to FIR filters. CIC filters are a class of FIR filters, but FIR filters have a much wider array of applications. I am not sure this comparison is useful. But to the extent that it is, I think we should also consider comparing to IIR filters. But of course that is a can of worms. TCMike 03:38, 27 December 2006 (UTC)
is partially correct. However, the number of bits at each stage of the filter is affected by the decimation or interpolation rate, as well as the gain of the filter. The gain of the filter for a decimation or interpolation ratio in the form of 2N is 1.0, and for decimation or interpolation ratios not equal to 2N, the gain is between 0.5 and 1.0.

The Hogenauer paper abstract states:
â | A class of digital linear phase finite impulse response (FIR) filters for decimation (sampling rate decrease) and interpolation (sampling rate increase) are presented. | â |
Consequently, comparisons to FIR filters was made in the abstract of the paper that introduced the CIC filter. Ra2007 ( talk) 16:37, 17 December 2007 (UTC)
