| Abstract: | In order to simulate the PCM30/32 channels digital telephone transmitting system with System View simulation software,based on the system chart consisting of simulation subsystems,the simulation circuit diagrams are proposed for TS8 channel audio signal sampling,quantization,coding serial-parallel conversion,division,digital-analog conversion,time-slot passing pulse generating and 32 channels PCM audio signals time-division multiplexing.Moreover the principle of the circuits is explained in detail.At the same time,the simulation receiving and transmitting shapes of TS8 channel audio signal are displayed clearly.Finally,the simulation effect is also analyzed. |
