3) In a processor these are 120 instructions . Bits needed to impliment this instructions
[a] 6 [b] 7 [c] 10 [d] none
Ans: b

4) In 8085 microprocessor READY signal does.which of the following is incorrect statements
[a]It is input to the microprocessor
[b] It sequences the instructions
Ans : b

5) Return address will be returned by function to
[a] Pushes to the stack by call
Ans : a

result=temp*10+ result;
Ans : 3267

7) If A>B then
else B>C then
in this , for 75% times A>B and 25% times B>C then,is 10000 instructions
are there ,then the ratio of F to G
[a] 7500:2500 [b] 7500:625 [c] 7500:625 if a=b=c else 7500:2500

8) In a compiler there is 36 bit for a word and to store a character 8bits are needed. IN this to store a character two words are appended .Then for storing a K characters string, How many words are needed.
[a] 2k/9 [b] (2k+8/9 [c] (k+8/9 [d] 2*(k+8/9 [e] none
Ans: a

9) C program code
int zap(int n)
if(n<=1)then zap=1;
else zap=zap(n-3)+zap(n-1);
then the call zap(6) gives the values of zap
[a] 8 [b] 9 [c] 6 [d] 12 [e] 15
Ans: b

10) Virtual memory size depends on
[a] address lines [b] data bus
[c] disc space [d] a & c [e] none
Ans : a

12) Critical section is
[b] statements which are accessing shared resourses
Ans : b

11) load a
mul a
store t1
load b
mul b
store t2
mul t2
add t1
then the content in accumulator is
Ans : a**2+b**4

12. Add 79H and 86H and tell the contents of flags

13. Scr is used for _____ ( ac, dc , both )

14. Push pull amplifier is used to remove which harmonics ( even , odd , both )

15. PAM is demodulated using ___ ( low pass filter , high pass filter )

16. 16k memory is needed. How many chips with 12 address buses and 4 data buses are needed.

17. AM wave is detected using _________ detector

18. Which flip flop is used for shift registers

19. Program counter does what __ (stores a memory address, address of the present instruction)

20. In a bistable multivibrator communication capacitor is used for ______ ( speed up response , ac coupling)

21. Totem pole is what?

22. Time costant for an integrator and differentiator should be ( small , high etc.)

23.TV waves are __ ( sky waves , space waves etc.)

24.Which configuration has highest i/p imp. ( ce , cb , cc )

25. Parabolic antenna with 2degree angle. What is its directivity.

26. Given 10 mhz pe modulation and we got a 100 mhz band. How many channels can be there
