Based on Direct Digital Synthesis (DDS) theory, using AT89C52 microcontroller as a control device, the AD9850 DDS device type to design a signal generator. Gives the signal generator hardware design and software design parameters, the system can output sine wave, square wave, and wide bandwidth, high frequency and stability, wave good. The signal generator has a stronger market competitiveness, in the frequency hopping, radio communication technology has relatively broad prospects for development.
