FIELD: computing appliances.
SUBSTANCE: invention relates to computer engineering and radio engineering, is intended for synthesis of frequency-modulated signals and can be used in systems of radar and communication. Digital computing synthesizer comprises a first memory register 1, a first digital frequency storage 2, a second memory register 3, a second digital frequency storage 4, adder 5, digital accumulator of phase 6, functional converter code-sinus 7, digital-to-analogue converter (DAC) 8, reference generator 9, unit of formation and delay 10. Digital inputs of the digital synthesizer are inputs of the first and second memory registers, and its analog output is the DAC output.
EFFECT: high rate of changing frequency of frequency-modulated signals.
