PANORAMIC RECEIVER Russian patent published in 2014 - IPC H03J7/32 

FIELD: radio engineering, communication.

SUBSTANCE: present invention relates to radio electronics and can be used to determine carrier frequency and type of modulation of signals received in a given frequency band. The panoramic receiver comprises a receiving antenna 1, an input circuit 2, a search unit 3, a high frequency amplifier 4, a heterodyne 5, mixer 6, an intermediate frequency amplifier 7, amplitude detectors 8, 16.1, 16.2 and 16.3, a video amplifier 9, a frequency sweep device 10, cathode-ray tubes 11, 17.1, 17.2, 17.3, 20, 24 and 31, a switch 12, a phase doubler 13.1, a phase quadrupler 13.2, an eight-times phase multiplier 13.3, a phase halver 14.1, a four-times phase divider 14.2, an eight-times phase divider 14.3, band-pass filters 15.1, 15.2, 15.3, 27 and 29, switches 18, 21 and 25, frequency detectors 19, 23 and 30, 90° phase changers 22 and 28.

EFFECT: high reliability of visual recognition of composite signals with single- or two-fold offset phase-shift keying.
