Abstract:
Apparatuses (and methods of manufacturing same), systems, and methods concerning polyphase digital filters are described. In one aspect, an apparatus is provided, including at least one pair of subfilters, each having symmetric coefficients, and a lattice comprising two adders and feedlines corresponding to each of the at least one pair of subfilters, each having symmetric coefficients. In one aspect, the apparatus is a polyphase finite impulse response (FIR) digital filter, including an interpolator and a decimator, where each of the interpolator and the decimator have at least one pair of subfilters, each having symmetric coefficients, and a lattice comprising two adders and feedlines corresponding to each of the at least one pair of subfilters, each having symmetric coefficients.

Claim (Index 11):
A method for a polyphase decimator, comprising:\n adding, by a first adder of a pair of adders, a first output and a second output of the plurality of outputs and providing the added outputs as input to a first subfilter of a pair of subfilters with symmetric coefficients, wherein the pair of subfilters is part of a bank of R subfilters; subtracting, by a second adder of the pair of adders, the second output from the first output and providing the subtracted output as input to a second subfilter of the pair of subfilters; and generating, from an output of the bank of R subfilters, a stream of N samples as output of the polyphase decimator, wherein the symmetric coefficients of each of the one or more pairs of subfilters are transformed from an initial pair of antisymmetric coefficients h m  and h R\u2212m , R being a total number of subfilters, and m being a subfilter index, where m=1, 2, . . . , R.
