problem1. prepare down the types of Multiplexing techniques.
problem2. Give two benefits of “Multiplexing”.
problem3. Given the total duration for the signal are 8 ns. What is the bit rate for signal depicted in the diagram below?
problem4. Suppose a 4 KHz bandwidth telephone line. When the signal is 10 V, the noise is 15 mV. What is the maximum data rate supported by this telephone line? Demonstrate your workings clearly.
problem5. describe how the “Differential Manchester Encoding” method works and draw the encoding signal of the following bits: 0 1 0 0 1 1 0 1 0 0.
problem6. What is the differentiation between a multicast, unicast, and broadcast address?
problem7. List and briefly describe any five benefits of using optical fibre.
