Two schemes of the digital direct frequency synthesizer are considered: classical one and the scheme based on the system of residual calculus. The main reasons for advent of noise components and the ways to enhance the output signal characteristics are analyzed. The different schemes of the digital synthesizers are simulated with the use of the computer.
