Patent ID: 8589461

Claim:
A digital device for decimating an initial data signal having an initial data rate R, to a final data signal having a final data rate R″, the digital device comprising: a coefficient generator configurable to calculate a plurality of coefficients, wherein the calculating is based on the final data rate R″ and a sampling rate P; a decimation unit comprising a plurality of filters configurable to: condition the initial data signal to generate a conditioned data signal conditioned for decimation to the final data rate R″, wherein the plurality of filters conditions the initial data signal by multiplying data points in the initial data signal by the plurality of coefficients; and decimate the conditioned data signal having the initial data rate R using a base decimation factor N to generate an intermediate data signal having an intermediate data rate R′; and a sampling unit configurable to sample the intermediate data signal having the intermediate data rate R′, wherein said sampling unit is configurable to use the sampling rate P to generate the final data signal having the final data rate R″.
