摘要
A decimator of the type having a decimation factor of K, is implemented by a finite impulse response (FIR) filter network of length N. The filter network includes N/K accumulators each of which arithmetically combines samples of an input signal as multiplied by a corresponding set of K network branches, and provides a corresponding output sample. The N/K output samples from the accumulators are provided sequentially at the filter output prior to arrival of the next set of N input signal samples at the filter input.
