Question 1

The number of edges in a regular graph of degree D and N vertices is equal to

Question 2

In pipe and filter architecture, creating regular new data is implemented by:

Question 3

A communication link is to be set up between two stations 100 km apart using antennae to transmit 1 kW power. The operating frequency is 100 MHz and the directivity of the two antennae is 1.64. The maximum received power would be

Question 4

Assertion (A): In a step index fibre, for single mode operation, the fibre parameters should be tailored such that the V- parameter is less than 2.408.
Reason (R): Modal fields of step index fibre are represented by Bessel functions Jn(x) in the core and modified Bessel functions Kn(x) in the cladding. The first zero for J1(x) falls at x = 2.408.

Question 5

Server X sends bit 1 with data key 100101 while server Y sends bit 0 with data key 010110. What will receiver obtain for server X, when two binary signals are send at same time with 0 coded as -1 and 1 coded as +1 with noise signals as 0, +1, -1, 0, 0, -1.

Question 6

In pyramidal horn antenna, the value of K is around:

Question 7

A single mode fibre does not suffer from which type of dispersion?

Question 8

In an optical fiber, n1 is refractive indices of core and n2 is refractive indices of cladding, the correct relation among two refractive indices is:

Question 9

Consider the following advantages of optical fiber-cables:
1). Small diameter
2). Immunity to cross talk and electromagnetic interference
3). Laser and LED modulation methods lend themselves ideally to digital operation
Which of these advantages are correct?

Question 10

What is the default behavior of R1 when PC1 requests service from DHCP server?
