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.
Q. With a cross sectional view, explain the working of a depletion type MOSFET Draw a biasing amplifier circuit DEPLETION-TYPE MOSFET: Two types of FETs: JFETs and MOSFETs. MOS
Q. An op amp has an open-loop frequency response as shown in Figure. (a) Find the approximate bandwidth of the circuit using this op amp: (i) With a closed-loop voltage gain
Introduction The purpose of this experiment is to examine the operation of the floating-point unit. Procedure 1. Show how the number 355.6 is converted into a normalize
Design a low noise amplifier using an Infineon RF transistor BFP640. The amplifier is to be used to amplify the L2 GPS signal and so the centre frequency is 1227MHz and bandwidth 4
Global Positioning System: For power utilities, the basic objective of using Global Positioning System (GPS) and GIS should be to: enhance the efficiency of transmissio
Q. Find the rate of information transmission? If the time occupied in transmitting each binary digit is 1 µs, find the rate of information transmission if 1 baud is equal to 1
Explain the Synchronous Machines? A synchronous machine, unlike an induction (or asynchronous) machine, only develops torque at a fixed, so called, synchronous speed - n s whi
atomic absorption theory
Q. A balanced three-phase, wye-connected, 2400- V, 60-Hz source supplies two balanced wye- connected loads in parallel. The first draws 15 kVA at 0.8 power factor lagging, and the
Q. What do you mean by Exponent? The exponent field needs to represent both negative and positive exponents. To perform this, a bias is added to the actual exponent in order
