FIELD: radio engineering, communication.
SUBSTANCE: invention relates to frequency selection and filtration of radio signals. A selection method of radio signals consists in the fact that out of N selection circuits there chosen is a selection circuit with the widest band-pass, for which a suppressing signal is fully or the maximum possible part of its power is beyond its band-pass. If the suppressing signal is within the band-pass of the selection circuit with the narrowest band-pass, then a selection circuit with the widest band-pass is chosen. A device for determining the interference situation includes N selection circuits, N detectors, N-1 comparison units, N-1 or N threshold devices and a decision device with N-1 or N inputs. This device produces a selection signal of the selection circuit as per the specified method. A radio signal selection device includes N selection circuits and a controlled switch. With that, the decision device can control the choice of the selection circuit through control of the switch in accordance with the method.
EFFECT: technical result consists in the adaptation of radio signal selection devices to the interference situation, as well as a possibility of control of their power consumption.
