FIELD: physics. ^ SUBSTANCE: invention can be used in the radio receivers working in conditions of both narrow-band, and broadband noises, operating in frequency band of the useful signal, at the small relation signal/hindrance. Method lies in allocation of the useful signal and noises of the information about bending around and phase of intermixture from input intermixture and the subsequent non-linear processing of the obtained information on a bending around input intermixture of the useful signal and noises. The device of noises inhibition contains four multipliers, two filters of the inferior frequencies, the mixer, the band-pass filter, two phase shifters on ?/2, the transformation block quarter-phase components in polar co-ordinates, the block of transformation of polar co-ordinates in the quarter-phase components, the processing block, the generator of the basic signal, two ADC and two DAC. ^ EFFECT: more simple inhibition of noises without dependence from noise amplitude probability density and exception of inhibition of the useful signal on exit of device of inhibition of noises at action of noises of low power and for lack of noises. ^ 2 cl, 5 dwg |
