Abstract

To produce the smooth waveform with the stable frequency,this paper presents a design method of sine signal generator′s function circuit which is based on the DDS theory.It mainly introduces the application of DDS technology in the waveform generator′s circuit and shows the principle of designing a DDS chip with FPGA,and the process of sin/cos and 32 sequence signal generator is treated.It is obvious to see that waveform generated by sine signal generator has some advantages,such as smooth and stable waveform,stable frequency and high resolution.
