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.
I want to know basic electricity
There are zillions of things in electronics known as encoders. You can look up LCDs and NAND gates as well and this is actual basics.

Q. Sampling of digital communication systems? Sampling of an analog signal makes it discrete in time. A bandlimited signal can be recovered exactly from its samples, taken peri
Q. We have discussed three different color spaces: RGB, HSI and CMY(K). Specify the need for multiple color spaces. Why can we not use only one? Q. A telescope in an observatory
Flag Registers Flag register is also an 8 bit register. Out of 8 bit five are defined as flags to indicate status of the accumulator hence it is also called status reg
Q. What are the different types of coupling in amplifiers? The coupling between stages of amplifications may also be used to classify amplifiers. There are four main groups: di
PRINCIPLE OF LED
Q. Describe Common-Mode Rejection Ratio ? When there is a common-mode input voltage, i.e., when the input signals are equal and greater than zero, the output voltage of an idea
