FIELD: physics, radio. ^ SUBSTANCE: invention concerns radio engineering and application as shapers of noises in transmitters of noises of different function, and also in radio communication resorts can find. Generator of the broadband frequency-modulated signal contains the shaper modulating oscillations and the self-oscillator, the generator of a signal with a continuous spectrum, the multiplication block, a loading, thus the shaper modulating oscillations are contained by the shaper of the normalised noise, the shaper of sawtooth impulses, the shaper of a white noise and the adder, and the self-oscillator contains the tunable shaper of a constant voltage and the generator controllabled a voltage. ^ EFFECT: expansion of instantaneous spectrum of signal, decrease in level of autocorrelation noises. ^ 3 dwg |
