FIELD: radio equipment.
SUBSTANCE: invention relates to radio engineering and can be used in noise-protected communication systems using noise-like phase-shift keyed signals, and enables to generate signals in the wavelength bands of VLF-VHF in digital form. Generator comprises frequency synthesizer (1), shaper of orthogonal pseudorandom sequence (2), pseudorandom sequence generator (3), multipliers (4,6), phasing device (7), adder (8), phase calculator (9), read-only memory (10) of cosine and sine table, digital-to-analogue converter (11), band-pass filter (12), amplifier (13) and modulo two adder (14).
EFFECT: reduced requirements for element base high-speed performance.
