Time will not be enough to complete the paper start with verbal and move to technical and at last do the maths... The technical aptitude questions are different for IT and Non IT stream...
The few technical questions I remember are
1. Which of following dissipates least power?
a.TTL
b.ECL
c.RTL
d.CMOS [ans]
2. What is the laplace transform of unit impulse function?
Ans.1/s.
3. The resistor is given voltage V=150 sint .what is the power dissipated?
4. How to find the value of Z in theveins theorm ?
Ans sc voltage source and oc current source.
5. If in addition of excess-3 code the sum exceeds 9 then what we hav to do?
Ans subtract it by 0011
6. A signal is modulated having modulation index 3 and 4 .what will be resultant M.I
Ans 5[srt of m1+m2]
7. IC timer 555 can be used as?
a. astable mv
b. monostable mv
c .freq divider
d. all[ans]
8. Give the contents of SP & HL pair after the execution of following statements
1002 LXI SP, 27FFH
1003 CALL 1006H
1006 PUSH H
Ans SP=27FFH HL=1006H
9. Phase margin of system is 125 what is its gain margin?
Ans -125 [not sure]
10. If the gate voltage is increased the n what will be the effect In MOSFET?
Ans Channel widens.
11. Current in the rotor of 3 phase induction motor is due to?
Ans Induction.
12. Question on transmission line with values of Zoc and Zsc given.Find the value of Zch?
Ans Zch =sqrt[ZocXZsc].
13. White noise has?
Ans Flat power spectral density.
14. The Transfer function of the system was given .find the no. of breakaway pts?
15. If a function has half wave symmetry its Fourier transform consist of?
A. only odd harmonics
B. only even harmonics
C. Both even & odd harmonics but no constant term
Some questions were from digital communication, digital electronics all questions were basic. |
