(a) List three types of Multiplexing techniques.
(b) Give two advantages of "Multiplexing".
(c) Given the total duration for the signal is 8 ns. What is the bit rate for the signal depicted in the diagram below?
(d) Assume 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? Show your workings clearly.
(e) Describe how the "Differential Manchester Encoding" technique works and draw the encoding signal of the following
bits: 0 1 0 0 1 1 0 1 0 0.
(f) What is the difference between a unicast, multicast, and broadcast address?
