Shang Jian-rong

Abstract

A program-controlled signal generator based on DDS was designed,which used direct digital frequency synthesis technology(DDS) and computer control technology,selected AD9851 and AT89S52 SCM of Analog Devices Company as control devices and realized software application design with C language.The signal generator can produce stable excitation signal and has high practical value.
