| Zusammenfassung: | FIELD: radio engineering, communication.SUBSTANCE: receiver has series-connected logic device, units for measuring signal carrier frequency and heterodyne frequency, heterodyne, mixer, intermediate frequency amplifier, detector, buffer register and storage device, wherein the intermediate frequency amplifier is single-channel and has filters tuned to different frequencies. The receiver also includes a filter number comparing unit connected between the output of the storage device and the input of the logic device.EFFECT: high probability of unique automatic determination of carrier frequency.1 dwg |
