The basic principle of the DDS technology is introduced,on the basis of which a signal generator system is realized,using a single chip machine AT89S52 to control the AD9850 chip.The results of theoretical analysis and experiments show that the system can produce sine wave,triangular wave and square wave,of which the amplitude and frequency can be adjusted.The output signal has a wide frequency band,high precision and high stability.

Key words: Direct Digital frequency Synthesis (DDS);AD9850;signal generator;AT89S52
