Abstract:
In this paper，a method of signal generator design based on AD9833，a DDS chip，is proposed，and hardware circuit structure and software program flow chart are introduced． Optional waveform and adjustable frequency can be realized by this method． With the MCU as a central control unit，and setting up the parameters of the source of the signal through the keyboard，the output signal＇s frequency can be changed from 0Hz to 12. 5MHz． The experimental results show that this signal generator has many advantages such as low cost，flexible setting，high precision and good stability．
