| Abstract: | Direct Digital Synthesis （DDS） technology is widely used in the field of modern communications, for its low phase noise, fast FM （frequency modulation） speed, small size and high frequency resolution. This paper introduces the working principle and characteristics of DDS, and presents the design circuit which uses single-chip microcomputer to control AD9910 DDS chip to generate high-performance signal. The experimental instrument test results show that the signal produced by the circuit can meet the users＇ need of waveform, frequency, amplitude, and phase. |
