Question 1
(a) Describe the functions of the modulator and source encoder in a digital communications system.
(b) By using appropriate examples, distinguish between the simplex and half duplex mode of communication.
(c) Briefly illustrate what is meant by the physical topology of a network. Given that there are n devices in a network, what is the number of cable links required for the following topologies:
(i) Mesh (ii) Ring (iii) Bus (iv) Star
(d) Identify which layer of the OSI model each of the five functions below is most likely to belong to. It is also possible that one or more of the functions cannot be mapped to an OSI layer. If this is the case, explain why.
(i) Translating between EBCDIC to ASCII (ii) Defining the pin-outs in a connector used to attach to a network cable (iii) Generating error correction codes for packet error correction (iv) Arbitrating between multiple nodes attached to a single medium (v) Providing an interface to a visual packet monitoring program
(e) Why is digital transmission better than analog transmission over a long distance where repeaters are needed in any case? Give two advantages of digital transmission over analogue transmission.
Explain the terms dielectric constant and dielectric loss. Dielectric Constant or Permittivity: all insulating materials possess an electrical capacitance. The capacitance of

Q. What is power gain? Power gain is the ratio of power delivered to the load to power delivered to the amplifier is the power gain. A p =P o /P i =V o I o /V i I s
State by inspection (i.e. without performing any formal analysis) all you can about each of the periodic waveforms shown in FIGURE 1 in terms of their Fourier series when analysed
Representation of Negative Number: As mentioned in chapter 1 in 8085 negative numbers are represented in 2 complement form and subtraction is performed using 2 comple
Q. When the two-wattmeter method for measuring three-phase power is used on a certain balanced load, readings of 1200W and 400W are obtained (without any reversals). Determine the
The site 450 kVA load is actually a three-phase, six pulse thyristor rectifier feeding a dc bus. Assuming that the voltage waveform at the site 11 kV bus is purely sinusoidal, calc
A photodiode is made to detect light quickly a solar cell is made to collect energy from light. They are both typically silicon diodes, but modified to meet their dissimilar requir
Requirements of equalizer connection
Q. Illustrate Inductance with example? An ideal inductor is also an energy-storage circuit element (with no loss associated with it) like a capacitor, but representing the magn
