DATA CODING/DECODING DEVICE Russian patent published in 2003 - IPC

FIELD: data coding and decoding devices; synchronous telecommunication systems. SUBSTANCE: device has data transmission unit and data reception unit connected to opposite ends of communication channel; data transmission unit has sync signal generator, coder, and group of output amplifiers; sync signal generator output functions as first synchronizing output of device; group of inputs of data transmission unit functions as group of data inputs of device; group of coder outputs is connected to inputs of group of output amplifiers whose outputs are connected to twisted pairs of communication channel wires; data reception unit has group of input amplifiers, decoder, first register, delay circuit, and inverter; group of outputs of data reception unit functions as group of data outputs of device. Transmission speed is enhanced due to using coding circuit with guaranteed variation of channel signal state in adjacent time steps. EFFECT: enhanced data transmission speed. 1 cl, 5 dwg
