(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?

Q. Explain the working of a darlington pair? This is two transistors connected together so that the current amplified by the first is amplified further by the second transistor
Types of Field-Effect Transistors The channel of a FET (field-effect transistor) is doped to produce either an N-type semiconductor or a P-type semiconductor. The drain and so
Explain the meaning of Ring Counters? A ring counter is fundamentally a circulating shift register in which the output of the most significant stage is fed back to the input of
Q. A commercial FMstation broadcasts a signal with 180-kHz bandwidth when |f(t)|max = 2 V. Find kFM for the modulator if the spectral extent of f (t) is 30 kHz, by using Carson's r
