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