Design of signal source based on SCM and DDS technology
Li Zhen · Modern Electronics Technique · 2014
The principle of direct digital synthesizer(DDS)technology is introduced briefly in this paper. A design schemeof a signal source based on AD9832 and 80C51 MCU is proposed. The hardware interface design and partial software codes ofthe signal source are discussed in this paper. The testing results are offered. The type of signal source,under control of soft-ware,is easy to be modulated,and has high accuracy and a bright application prospect.
