Abstract
This article presents is performed and, on this basis, a model of spectrum of the output signal of multichannel digital synthesizer. When such circuits operate on a common load, additional spectral components appear in their output spectrum caused by errors in the formation of this signal. The use of different output signal models depending on the internal structure of the multichannel circuit and error sources complicates spectrum analysis. The article proposes a model of a sampled signal that takes into account the main sources of errors in its formation. Expressions are obtained for calculating the complex spectrum of the output oscillation of a multichannel digital synthesizers circuit foe various operating modes.
