A digital frequency synthesizer generating digital samples has been designed and contructed. In this paper, the generation of summed sinusoid waveforms is accomplished by implementing two accumulators, accessing the sine table twice and summing the sine values before outputing to the converter. The sine values are inputted to digital-to-analog converters followed by low-pass filter to produce analog sinusoids. A implementatio by using single chip microcomputer, based on table lookup method is introduced.
