FIELD: physics; communication.
SUBSTANCE: present invention pertains to electronics and computer technology, meant for synthesising frequency and phase modulated signals and can be used in radar, navigation and adaptive communication systems. The digital synthesiser of frequency modulated and phase modulated signals contains a reference generator, delay unit, first memory register, first digital accumulator, second memory register, second digital accumulator, adder, code converter, digital-to-analogue converter, low pass filter, third memory register, frequency divider with varying division factor, fourth memory register and a third digital accumulator.
EFFECT: provision for independent control of synthesised signals on frequency and on phase.
