Abstract : Research performed on a 6-channel Pulse Code Modulation (PCM) system using new techniques is described. Circuits were designed, constructed and tested before being installed in the PCM system. Multiplex logic was laid out and constructed to be used in the system. Special sync circuits are described to enable complete understanding of their operation. A complete 6-channel PCM system was constructed and tested with the operation of one channel to give voice demonstration. Thus the feasibility has been successfully demonstrated in the use of magnetic techniques. (Author)
