Implementation of Three-phase Sinuous Direct Digital Synthesizer Based on FPGA
Jin Wu · Telecommunication Engineering · 2011
Based on combination of FPGA and D/A,a three-phase sinuous signal generator whose phase and frequency can be modified is designed and realized by using DDS.Sinuous modulation waveforms come from lookup table.Data of sinuous waveforms only in 1/4 sinuous cycle is required to be stored in ROM so that the internal hardware resource of the FPGA is reduced.Simulation and tests show that the output waveform can meet the design specifications,which proves the design is correct and feasible.
