FIELD: digital signal transmission over radio links and wirelines.
SUBSTANCE: device designed for synchronous data transmission using multiposition kinds of keying and redundancy coding, as well as for using small-base noise-like signals is available in two design alternates. That of first design alternate has demultiplexer, two delay circuits, two subtraction units, and two squarers. Device of second design alternate has shaper-distributor of total anticipatory, total intermediate, and total delayed signal readings, two delay circuits, three subtraction units, and two squarers.
EFFECT: enhanced noise immunity of phase discriminator and symbolic synchronization devices built around it.
