FIELD: computer engineering.
SUBSTANCE: invention relates to computer engineering and radio engineering, is intended for synthesis of two-frequency complex frequency-modulated signals and can be used in radar and communication systems. Digital computing synthesizer of double-frequency signals contains reference generator, unit of formation and delay, first and second memory registers, first, second, third, fourth digital storages, multiplexer, converter of codes, digital-to-analogue converter (DAC). Digital inputs of the digital synthesizer are the inputs of the first and second memory registers and the control input of the multiplexer, and its analog output is the output of the DAC.
EFFECT: enabling synthesis of double-frequency frequency-modulated signals.
