Abstract

The invention relates to radio engineering and communications. The purpose of the invention is to expand the frequency range of the generated random signals. Gd contains multipliers 1 and 4 frequencies, phase manipulators 2 and 6, gr.r 3 sinusoidal oscillations, shaper 5 clock pulses, matching unit 7 and rr 8 pseudo-random sequence of pulses, consisting of el-delay 9, phase shifter 10, threshold elec 11, amplitude detector 12, adder 13 and trigger 14. The signal from r-s 3 is fed simultaneously to multiplier 4, which provides the multiplier 1 and driver 5, and to phase manipulator 6 connected through matching unit 7 to the main output of Mr. random signals. The sinusoidal signal from the multiplier 1 is fed to the phase manipulator 2, the output of which is the additional output of a Mr. random signal. The formation of phase-shifted pseudo-random signals with an additional phase manipulator 2 provides for the expansion of the frequency range of the generated random signals. 1 il.
