摘要: A decimation system comprising a plurality, L, of cascaded Finite Impulse Response (FIR) filters. Each filter has transfer function the form H(z)=(1+z −1 ) N , where is an integer. FIR performs by common factor I. The filters together achieve result substantially identical to that th -order CIC (that is, having integrator stages) I L .
