Abstract:
Embodiments are described of devices and methods for processing a signal using a plurality of vector signal generators (VSGs). A digital signal may be provided to a plurality of signal paths, each of which may process a respective frequency band of the signal, the respective frequency bands having regions of overlap. The gain and phase of each signal path may be adjusted such that continuity of phase and magnitude are preserved through the regions of overlap. The adjustment of gain and phase may be accomplished by a complex multiply with a complex calibration constant. The calibration constant may be determined for each signal path by comparing the gain and phase of one or more calibration tones generated within each region of overlap. Each signal path may comprise a VSG to convert the respective signal to an analog signal, which may be combined to obtain a composite signal.

Claim (Index 8):
An apparatus for processing a digital signal, the apparatus comprising:\n a plurality of parallel signal processing pathways, each of the parallel signal processing pathways configured to:\n frequency-shift a respective component signal comprising a respective frequency band of interest of the digital signal, the frequency band of interest having a region of overlap with a frequency band of interest of at least one other component signal, such that a center frequency of the frequency band of interest is shifted to baseband; \n shape a frequency response of at least the respective frequency band of interest, using a digital filter; and \n convert at least the frequency band of interest to a respective analog signal, wherein the component signals are phase-locked; and \n a signal combiner configured to combine the respective analog signals to obtain a composite signal, wherein a shape of the digital filter has a reduced gain in at least a portion of the regions of overlap to reduce artificial increases in magnitude in the composite signal.
