| Abstract: | On the basis of direct digital synthesis （DDS） principle, a signal generator was designed, using AT89C52 single chip machine as the control device and adopting AD9850 type DDS device. Hardware and software design parameters were given. The system can output sine wave, square wave with wide frequency band, high frequency stability and good waveform. The signal generator has stronger market competitiveness, with wider development prospect in frequency modulation technology and radio communication technology fields. |
