DATA TRANSFER DEVICE Russian patent published in 2003 - IPC

FIELD: data transfer devices; synchronous telecommunication systems. SUBSTANCE: device has data transmission and reception units connected to opposite ends of communication channel; data transmission unit has three EXCLUSIVE OR gates, two amplifiers, two flip-flops, shift register, and sync pulse generator. Data reception unit has two amplifiers, AND and OR gates, inverter, phase-locked loop unit, three flip-flops, and two pulse shaper units. Device transmits encoded signal incorporating serial data stream accompanied by bit and frame sync pulses over communication channel, variation in channel state in each bit interval being guaranteed. EFFECT: enhanced transmission speed, reduced level of cross-talk noise. 1 cl, 19 dwg
