(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?
(g) List and briefly describe any five benefits of using optical fibre.
Determine and plot for 5 keV to 100 MeV the fraction of the total cross section due to each of the four interaction processes for (a) hydrogen, (b) nitrogen,
Describe hall effect?also describe it''s mathematical analysis and it''s properties
What is an USART? USART stands for universal synchronous/Asynchronous Receiver/ Transmitter. It is a programmable communication interface that can communicate by using either s
Three transformers are provided with the following rating values: 1) 2400/240 V, 55kVA, Req1 = (0.1 + 0.0Y) Ohm and Xeq1 = (0.15 + 0.XX) Ohm. 2) 240/120 V, 25kVA, Req1 = (0.1
Explain the NEG instruction. NEG: Two's complement or arithmetic sign inversion (NEG). The NEG instruction two's complements a number that means that the arithmetic sign of a
Q. Give suitable block diagram to explain the working of electronic multimeter. Sol. An electronic multimeter is a laboratory instrument which is capable of measurement of
Q. Consider the non inverting amplifier. Let R i = 1k and R f = 2k. Let the op amp be ideal, except that its output cannot exceed ±12 V at a current of ±10 mA. (a) Find the
Q. Explain Current-to-Voltage Amplifier? The basic circuit is shown in Figure, which is similar to that of an inverting amplifier. The - input is connected directly to a curren
Q. Explain Demodulation of DSB? Demodulation of DSB SC AM signals requires a synchronous demodulator, which is also known as coherent or synchronous detector. That is, the demo
Q. A gyrator is sometimes used in integrated circuits to simulate inductances. Consider the circuit of Figure consisting of a gyrator. (a) Show that the impedance as seen to the
