| Abstract: | The article designs a sinusoidal signal generator which adopts the AT89S52 as core control devices to control the two DDS chips of AD9850 directly and achieved through parallel control mode. A differential amplifier chip AD830 is selected for sinusoidal signal amplitude adjustment. The system has the function of variable frequency and phase, adjustable amplitude, and can output a stable phase and amplitude modulation. |
