Summary<BR>This paper mainly introduces the research and implementation of DDS signal generator based on FPGA. Firstly, this paper introduces the development course and characteristics of the signal generator and the DDS signal generator, then introduces the research status and program demonstration of the subject at home and abroad, and then describes in detail the mif file of waveform data generated by using MATLAB to generate the waveform data of each waveform on the Development Board, which is dominated by the FPGA chip. The quartus II12.0 is programmed to produce DDS and use the PS2 keyboard to control the waveform, the phase and frequency of the output, and the picture of what waveform is displayed using VGA; DDS signal generators that can output square, sine, triangular, and jagged waves can be output.
