发明名称 OVERSAMPLED SYNTHESIZER SYSTEMS AND METHODS
摘要 Systems and methods for combining digital input signals in an oversampled synthesizer system are provided. An inverse Fourier transform component is configured to receive a plurality of digital input signals, having a first sampled rate, and produce a corresponding representation of a wideband signal as a plurality of parallel outputs. A plurality of digital filters are each configured to apply a transfer function to an associated one of the parallel outputs to produce a filtered output. A number of filters in the plurality of digital filters is less than a number of parallel outputs of the inverse Fourier transform component, such that at least one of the parallel outputs is not provided to any filter of the plurality of digital filters. An interpolation component combines the plurality of filtered outputs into a wideband digital output signal having a second sampled rate.
