If a sinusoidal signal of 1100Hz is flat top sampled at a rate of 1800Hz,& this signal is passed through an ideal LPF with cutoff 1KHZ,the o/p contains the following frequency components: (This question was repeated again in the same paper !!!) (a)only 800Hz (b)... (c)... (d)... 3. TRAP is _____interrupt (a)synchronus (b)asynchronus (c)hardware (d)... 4. When the instruction RST is executed, the control jumps to location: (a)0020 (b)0024 (c)0028 (d)none of the above 5.

Worst case algorithm is meant for the case (a)when sometimes favourable (b)when worst unfavourable (c)... (d)... 7. A semaphore with negative count n(s=n) has how many processes in the Q? (a)0 (b)n (c)n+1 (d)n-1 8. If in a PCM system the no of bits used is increased from n to n+1,the signal-to-noise ratio improves by (a)3dB (b)6dB (c)20ndB (d)24ndB 9. 2 trains of length 110m & 90 m travelling at 45kmph & 50 kmph respectively..when will they pass each other? (a)144mins (b)102mins (c).. (d)... 10. From a circular sheet of radius 10cm , 40% is cut off & from the remaining portion a cone is constructed, what is the ratio of the radius of the cone to its height? 11. If a vessel contains 56 litres of a mixture of milk & water in the ratio 3:2..what amount of water should be added to make the ratio 4:5? 12. 2 pipes fill a cistern in 12 mins,pipe A is 3 times faster than pipe b...if only pipe B has to fill the cistern ,how long will it take? (a)1hour (b)2hours (c).. (d).. 13. #define ADD(X,Y) X+Y main() { #undef ADD(X,Y); fun(); } fun() { int y=ADD(3,2); printf("%d",y); } o/p? Runtime error(linker error): _add undefined in module 14. Which of the following is illegal (a)void v; (b)void *v; (c)void **v; (d)all are legal 15. #define int INTEGER/*line1*/ #define INTEGER int/*line 2*/ main() { INTEGER p=10;/*line 5*/ printf("%d",p); } o/p? (a) compiler error at line 1 (b) compiler error at line 2 (c) compiler error at line 5 (d) No error,prints 10 ans:c |
