Patent ID: 8744025

Claim:
A system for pre-processing a digital input signal comprising: a digital down converter (DDC) configured to down convert and down sample at a DDC sample rate a spectral component of the digital input signal to baseband, while reducing bandwidth and sample rate to create a down converted signal at baseband; an interpolator configured to re-sample the down converted signal to produce a re-sampled signal with a new sample rate, wherein a dynamic range of the digital input signal is preserved and the new sample rate is different than the DDC sample rate; two or more down samplers configured to produce two or more down sampled signals associated with the down samplers, wherein the two or more down samplers are connected in series, with the re-sampled signal input to a first one of the two or more down samplers, wherein the two or more down sampled signals are output from each of the two or more down samplers connected in series; and a multiplexer configured to multiplex one of the group of: the digital input signal, the down converted signal, and one of the two or more down sampled signals to an output line.
