Abstract—

The design principles and the structural and circuitry solutions are described for digital computational synthesizers based on the method of direct digital synthesis of frequencies and signals. The structural and circuit diagrams of a digital computational synthesizer of complex wideband signals are presented. Using this synthesizer, it is possible to synthesize signals with amplitude, frequency, and phase modulations in the frequency range of 0.001−920 MHz.
