FIELD: electronic engineering; radio engineering.
SUBSTANCE: invention is intended for synthesis of frequency-modulated and phase-shift keyed signals and can be used in radar, navigation and communication systems. Digital computing synthesizer comprises (Fig. 1) reference generator 1, a forming and delay unit 2, memory register 3, a digital frequency storage 4, frequency correction unit 5, first adder 6, digital phase accumulator 7, phase correction unit 8, second adder 9, a code-sinus function converter 10, a digital-to-analogue converter (DAC) 11. Digital input of digital computer synthesizer is input of memory register, and its analog output – output of DAC.
EFFECT: technical result is possibility of crosstalk suppression and incidental amplitude modulation.
