After analyzing the defect of the inefficiency of resource utilization and the inaccuracy of the output frequency existing in the application of traditional DDFS,this paper presented a method of designing and implementing harmonic signal generator based on the improved Direct Digital Frequency Synthesizer(DDFS) technology.It probes into the enhancement of frequency accuracy and the compression of memory capacity.It is proved that,through the optimization of DDFS structure and the introduction of the new algorithm,the frequency accuracy and compression of memory capacity have been improved without affecting system speed and reliability.
