FIELD: radio engineering.
SUBSTANCE: synthesizer of frequency-modulated signals comprises a phase detector, a low pass filter, a controlled generator, a divider with an alternating division ratio (DADR), a reference generator, a divider with a fixed division ratio (DFDR), an information source, M (M>1) generators of sine and cosine components of manipulation frequencies, M scale amplifiers for sine outputs and M scale amplifiers for cosine outputs, the first and second switchboards, a controlled phase inverter, the first and second multipliers, a control unit, a summator, a quadrature signal shaper.
EFFECT: higher efficiency of digital information transfer, removal of limitation for transferred information.
