ERROR DETECTION DEVICE Russian patent published in 2010 - IPC H04B17/00 

FIELD: information technology.

SUBSTANCE: error detection device can be used to detect error character from a data sequence and measuring probability of transmitting information in digital channels, as well as in error analysers when monitoring operation quality of communication channels. The device has a first (1), second (2), third (3) and fourth (14) modulo-two-adders, a comparator (4), first (5), second (6), third (7), fourth (8) and fifth (15) flip-flops, first (9), second (10), third (13) and fourth counters (16), an AND element (11), a shift register (SR) (12), first (17) and second (18) switches, a code word shift register (19), a code word modulo-two-adder (20), a reference frequency selection unit (21) and a control unit (22).

EFFECT: broader functional capabilities of the error detection device, wider range of operating frequencies.
