1 st round:
    Written consist of 6 section.
     1: 15 quantitative
     2: 20 english
     3: 15 pictorial
     4: 15 mechanical related
     5: 40 electronics related
     6: 20 C programming without option

1. UJT starts conducting if its emitter is forwardbiased.
2. Schmitt trigger is otherwise called as----------.
3. Heart of Analog to Digital converter is comparator.
4. For differential amplifier CMRR value should be large.
5. The time constant for differentiator and integrator are small and large respectively.
6. Which gate act as parallel switch OR gate.
7. Which of the following is false (4 options will be given) 1+1 = 10.
(X+Y)(X+Z)= X+YZ.
8. Which of the following is dual to A+1 (4 options will be given) A.0 =   [reason: change + to . and 1 to 0].
A` . B` = (A+B) `.
9. The basic gate used for TTL logic NAND gate.
10. Which is not the specification for digital I.C Bandwidth.
11. Which is correct 1 0  1 =1.
12. Which logic is faster ECL.
13. Which is used for dynamic memory (FET, MOSFET, Transistor, and Flip Flop)?  
14. What is half adder it add two binary  input and give sum and carry.
15. What type of communication used in USART Half duplex.
16. What is the result of 1000>>2 0010 [right shift two times].
17. For counters Flip Flop is used.
18. Number of flip flops used in counter is equal to  number of bits in counter.
19. What is control bus in microprocessor output of microprocessor.
20. A 16 bit processor gets its name from Number of data bits.
21. A 12 bit address can access memory of 4 KB.
22. What is scratch pad temporary memory.
23. What does first machine cycle does  opcode fetching.
24. What is the delay in shift register (n+1)T (not confirmed check it out).
25. If X(t) of m terms and Y(t) of n terms then the total number of terms in convolution of X(t) and Y(t) (i.e) h(t) have m+n.
26. What is FIR finite impulse response filter.
27. The function y(t)=x(t) + t. sin(t) is time variant.
28. The system y(n)=x(n)+x(n-1) is a casual system.
29. The fourier transform of impulse signal is 1.
30. Given that sin(3t) find fundamental frequency 3/2Π.
[Reason: compare  sin(3t) and sin(ωt) ≡ ω=3 ≡ 2Πf=3 ≡ f=3/2Π].

2nd  round: Group discussion
      Politician peoples are role model for youth.

3rd  round: Technical(around 50 min)
They wil ask so many question on your project.
Next From basic C to up to pointers,
Set bit, clear bit, conditional  statement, code optimization, const char ptr , char const ptr, function ptr, storage classes , and so on
Last round: Hr


Don’t take Hr round easily.
