| Abstract | ||
| This research deals with a look to the process simulation system of first order PCM(pulse code modulation) multiplexer has been achieved by designing the system on the basis of implementing its functions using simple logic for the logic circuits (logic gates) . That the perception of the process simulation of the system had been considered in accordance with the rules of the International Union to meet the basic requirements of standardization (ITU-T) Rec. G.703, G704, G706, G732 and G823 related to line coding and pulse shaping, frame structure types (FAS, CRC-4, CAS and CCS), modified Communication Research Centre CRC-4 multiframe, errors detection and jitter tolerance respectively, are simulated. | ||
