FIELD: digital communications, namely engineering of devices for synchronizing digital information transfer systems with time compression of digital streams.
SUBSTANCE: synchronization device contains first and second random-access memory units, operation mode calibration block, frame synchronization combination decoder, information signals commutation block, first phasing block and generator equipment. Second phasing block, block for finding super-frame synchronization combination and block for finding super-frame synchronization are introduced into the device.
EFFECT: decreased time spent on searching for synchronism of digital transmissions with various types of modulation having super-frame structure.
