Waveform generation for the digital synthesis systems based on embedded hardware

Parametric estimation of the efficiency of periodical signals digital synthesis algorithms based on embedded hardware systems was performed. It was found that the level of the higher-order spectral components is reduced by changing the dimensions of the lookup table. The interpolation of sine function discrete values in the range 0-360 degrees provides the reduction of the ROM from 768 Mbit to 192 kbit. In this case, an increase of harmonic distortion doesn't exceed 5 percent.
