Design And Implement of Tri-phase Sinuous Direct Digital Synthesis Based on FPGA
Wei Yuan · Microcomputer Information · 2009
Based on combination of FPGA and D/A and using DDS to generate tri phase sinuous Signal Generator, which phase and frequency can be modified. Sinuous modulation waveforms come from lookup table. Data of Sinuous waveforms only in 1/4 sinuous cycle are required to be stored in ROM, which is constructed internal hardware resource of the FPGA. Simulation tests proved that the output waveform can meet the design specification, which prove the design is correct and effectively.
