The disclosure relates to improved direct digital frequency synthesizers. A synthesizer in one embodiment is comprised of an accumulator that provides a phase signal and an interpolator having two or more interpolation polynomials. The polynomial that processes the phase signal is selected by comparing ...

Direct digital frequency synthesizers (DDFSss) are generally implemented by successively scanning trough a lookup table stored in a read-only memory (ROM) and converting the recalled sine samples to an analog waveform via a digital to analog converter (DAC). This paper describes a new implementatio...
A complete characterization of direct digital frequency synthesizers; (DDFSs) is made, deducing exact expressions and general properties of these synthesizers. As an application example of the derived expression for the power spectrum density with phase quantization, an extremely simple algorithm is descr...
