Demulitplexing

• Uses the same physical mechanisms as multiplexing

  • Has to reflect the multiplexing mechanism

• Addressing

  • Input channel must select the proper output channel to receive each sub-channel

• Centralized implementations

  • Demuxer explicitly uses output channels

• Distributed implementations

  • Input channel is broadcast to all the output channels
  • Address decoder picks off the sub-channel as its data fly past
