(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.
