Abstract
A FIR digital filter comprises a plurality of cascaded subfilters all operable at the same sampling rate. At least one of the subfilters has a z-transform transfer function defined by a partially factorized, n.sup.th -order polynomial in z.sup.-1, where n>2 whose co-efficients are quantized. A process for deriving the z-transform transfer function of the filter is described.
