Abstract

Inventia se refera la un modulator-demodulator pentru transmiterea sincrona a informatiei prin cabluri torsadate, caracterizat prin aceea ca, cuprinde în structura sa un modulator alcatuit din 2 porti logice de tip SI, conectate la iesirea unui bist abil care sincronizeaza semnalele aplicate portilor logice si o alta poarta de tip SI pentru compensarea întârzierii de propagare a datelor bistabilului, un circuit de demodulare si sincronizare format dintr-un bistabil realizat cu niste porti logiceSI-NU, care furnizeaza la iesire semnalul de date, si o poarta logica de tip SAU - exclusiv, care are rolul de a recupera semnalul de ceas.The invention relates to a modulator-demodulator for synchronous transmission of information by twisted-pair cables, characterized in that it comprises in its structure a modulator consisting of 2 SI logic gates, connected to the output of a capable bistle which synchronizes the signals applied to the logic gates another SI gate to compensate for the propagation delay of the flip-flop data, a demodulation and synchronization circuit formed by a bistable realized with some logical gates SI-NU, which provides the output signal, and a logical gate type OR - exclusive, which has the role of recovering the clock signal.
