Digital signal e.g. finite impulse response signal, processing method for use in e.g. finite impulse response filter, involves processing signal, where two sets of factors are based on respective real and complex poles of transfer function

摘要

The method involves processing a digital signal e.g. finite impulse response (FIR) signal, based on a transfer function of a digital system, where the transfer function includes simple real poles and conjugate complex poles. Two sets of factors are based on each of the simple real poles and conjugate complex poles, respectively.
