Frequency-Division Multiplexing (FDM): On Example 1 Slide 1. Assume that a voice channel occupies a bandwidth of 4 kHz. We need to combine seven voice channels into a link with a bandwidth of 28 kHz, from 26 to 54 kHz. Show the configuration, using the frequency domain. Assume there are no guard bands. Frequency-Division Multiplexing (FDM): On Example 2 Slide 2. Seven channels, each with a 50 kHz bandwidth, are to be multiplexed together. What is the minimum bandwidth of the link if there is a need for a guard band of 3 kHz between the channels to prevent interference? Time-Division Multiplexing (TDM): On Example 1 Slide A A2 A1 A3 C2 82 A2 CI 81 AI 83 82 81 Frame 3 Frame 2 Frame 1 MUX CI T/3 Data are taken from each Iine at every T second Each trane is 3 time slots. Each time slot duration is T/3. 3. Assume that data rate for each input connection in figure above is 6 kbps. Find the new durations for a) each input slot, b) each output slot, and c) each frame. Time-Division Multiplexing (TDM): On Example 2 Slide 4. Assume that data rate for each input connection in figure above is 5 Mbps. A unit is 1 bit. Find the new durations for a) the input bit duration, b) the output bit duration, c) the output bit rate, and d) the output frame rate.
