Design of DDS Multi-Waveform Generator Based on MCU

Yuli Liu

Abstract

Based on direct digital frequency synthesis(DDS),the AD9852 AD9833 chips as the core,the MCU control,a kind of waveform generator,with a simple structure and excellent performance,that can output sine and cosine wave,square wave,triangle wave,is designed.This function generator has a wide range of applications,because it has characteristic by many virtues,for instance,a higher frequency resolution,faster frequency-switching,wide frequency bandwidth and easy integration of digital technology.
