Design of signal generator based on DDS
Hong Li · Ningxia Engineering Technology · 2009
In order to generating sinusoidal wave,the generator,based on DDS,uses the on-line programmable monolithic integrated circuit AT89S52 as the primarily controller,union direct digital frequency synthesis chip AD9850,which range is from 0.1 Hz to 1 MHz in 0.1 Hz frequency step.The system has simply structure with flexible control and higher precision signal.
