Some Sample questons from the Mains papers of ESE 2018 ET
1. For a microwave link, define all the components contributing to system gain. Determine system gain for a microwave link operating at 1-8 GHz carrier frequency. Each station has a 2-4 m diameter parabolic antenna fed by 100 m of airfilled coaxial cable. The distance between stations is 40 km. A reliability objective of 99-99% is desired. The terrain is smooth and climate is humid.
Assume feeder loss = 10-8 dB, branching loss = 4dB and gain of each antenna = 31-2 dB.   10
2. Five soldiers, A, By C, D, E, volunteer to perform an important military task if their following conditions are satisfied :
(i)Â Â Â Either A or B or both must go.
(ii)   Either C or £, but not both, must go.
(iii)Â Â Â Either both A and C go or neither goes.
(iv)Â Â Â If D goes, then E must also go.
(v)Â Â Â If B goes, then A and D must also go.
Define the variables A, B, C, D, E such that an unprimed variable will mean that the corresponding soldier has been selected to go. Determine the expression which specifies the combinations of the volunteers who can get the assignment.
3.Show the value of all bits of a 12-bit register that holds the number equivalent to decimal 215 in
(A)Â Â Â binary
(B)Â Â Â binary coded octal
©Â Â Â binary coded hexadecimal and
(D)Â Â Â binary coded decimal.
4. Derive the expression in time domain for the unit step response of second order system.  Â
5. A CPU with a 20 mHz clock is connected to a memory unit having access time of 40 nS. Formulate a read and write diagram showing respective strobe.
