= Cascaded integrator–comb filter
{wiki=Cascaded_integrator–comb_filter}
A Cascaded Integrator-Comb (CIC) filter is a type of digital filter commonly used in signal processing applications, especially in hardware implementations where a large number of taps (filter coefficients) would be computationally expensive or impractical. CIC filters are particularly useful for operations like decimation (downsampling) and interpolation (upsampling). \#\#\# Key Characteristics: 1. **Structure**: - A CIC filter consists of two main components: an integrator section followed by a comb section.
