DEVICE FOR TWO-LEVEL CODED SIGNAL RECEPTION AND SYNCHRONIZATION Russian patent published in 2006 - IPC H03M5/12 H03M5/14 H03M5/16 

FIELD: computer engineering; reception of differential two-level coded signal of sequential self-synchronizing code with conversion to two-digit digital signal and further noise-resistant execution of full synchronization function for this signal using input continuous timing pulse sequence.

SUBSTANCE: device consists of detector-transducer (6), inputs (19,20) of first and second components of differential two-level coded signal, triggers (1-5), NAND elements (7,8), AND (21-24), OR (15-17), negative OR (11-13), XOR elements (9-10), asynchronous delay component (14), clocked delay components (27), clock input (18), and four outputs.

EFFECT: increased noise immunity due to noise-resistant forming of output synchronized signal and outputs clock signals of bit synchronization, pause start and pause with obstructing filtration, synchronization of two-digit digital signal of two-level code 1B2B, as noise, with duration of signal changes not exceeding the threshold duration P*Tic for P≥2, where P - threshold number, Tic - duration of clock pulse period.
