DIGITAL SYNTHESIZER OF PHASE-SHIFT KEYED SIGNALS Russian patent published in 2019 - IPC H03L7/18 

FIELD: computer equipment.

SUBSTANCE: invention relates to computer engineering and radio engineering, is intended for synthesis of frequency-modulated and phase-shift keyed signals and can be used in radar and communication systems. Digital synthesizer of phase-shift keyed signals includes reference generator 1, unit of formation and delay 2, first memory register 3, digital frequency accumulator 4, digital accumulator of phase 5, adder 6, multiplexer 7, code converter 8, digital-to-analogue converter (DAC) 9, low-pass filter 10, second memory register 11, divider with variable division coefficient 12, third memory register 13. Digital inputs of the digital synthesizer are the inputs of the first, second and third memory registers and the control input of the multiplexer, and its analog output is the LPF output.

EFFECT: technical result consists in the possibility of synthesis of phase-shift keyed signals.
