FIELD: radio receiving equipment.
SUBSTANCE: invention relates to radio receiving equipment. The effect is achieved by the fact that the facsimile receiver contains a receiving antenna connected in series, a radio receiver, analog-to-digital demodulating devices (ADDD), a digital processor (DP) with appropriate software, on the monitor of which the received information is displayed line by line. The radio receiver consists of a preselector, amplifier and frequency converter connected in series. ADDD consists of serially connected frequency discriminator (FD), N additional serially connected FR, similar in circuit design and design to the original (regular) FD, threshold device, amplitude detector and analog-to-digital converter. Wherein the number of additional black holes is determined by the known information transfer rate.
EFFECT: improving the noise immunity of receiving facsimile information under conditions of intense fluctuation interference with constant energy and frequency-time resources of the radio channel.
