【应用笔记】理解CIC补偿滤波器(Understanding CIC Compensation Filters)
级联积分－梳状(Cascaded Integrator–Comb，CIC)滤波器，是一类硬件高效、线形相位FIR数字滤波器。
The cascaded integrator-comb (CIC) filter is a class of hardware-efficient
linear phase finite impulse response (FIR) digital filters. CIC filters
achieve sampling rate decrease (decimation) and sampling rate increase
(interpolation) without using multipliers. Altera’s CIC Compiler
MegaCore® function implements various CIC filters based on
Hogenauer’s method.an455.pdf
