Considered sources of noise and lateral components in the spectra of direct digital frequency synthesizers – DDS. A mathematical analysis of noise in this type of synthesizers. The method for reducing the periodic component in the output spectrum of direct digital synthesis. Application of the proposed method reduce the periodic component will reduce the level of lateral components in DDS synthesizers type. Methods of improving the quality of the spectral characteristics of the synthesized signal DDS. The proposed structure DDS with improved spectral characteristics. Application of the proposed structures synthesizers will reduce the level of spurs outside the band radio equipment that uses DDS. The methods and means of reducing the lateral spectral components in the output spectrum of the classical computational synthesizer based on accumulative adder. We found that it is possible to build a synthesizer with high tactical and technical characteristics of the algorithm used by Wheatley. The possibilities of the application of new mathematical approaches for building adders without a problem propagation delay signal transfer from the category in the category codeword. Consider a Boolean algebra operations over a couple of numbers and the theory of Galois fields to improve performance synthesizer. The mathematical apparatus will build a digital computer synthesizer with lower levels of lateral components in the spectrum of the output signal, due to some complications of the internal structure of the synthesizer using two additional adders and pseudo-random number generator.
