One Optimizing Method for DDS Pulse Waveforms based on Genetic Algorithm
Jing Zhang · Journal of Chongqing Institute of Technology · 2005
Direct Digital Frequency Synthesis(DDS) is a new technology of frequency synthesis,which possesses the advantages of high frequency resolution,fast frequency switching,super-wide relative band width,successive phases,total digitalization,etc.In fact,DDS is a technology for waveform synthesization that is able to output any waveform with high stability.This paper discusses the overshooting and ringing in the output signals in pulse-generating DDS,puts forward the methods to optimize pulse waveforms with the help of genetic algorithm so as to reduce overshooting and ringing,and demonstrates the methods with computer simulation.
