| 31. | For a 4096 x 8 EPROM, the number of address lines is |
|||||||
Answer: Option B Explanation: 4096 = 212 . |
| 32. | Assertion (A): A PROM can be used as a synchronous counter Reason (R): Each memory location in a PROM can be read synchronously. |
|||||||
Answer: Option D Explanation: PROM is a memory. It is not a counter. |
| 33. | A B C D + AB C D = |
|||||||
Answer: Option C Explanation: A B C D + A B C D = A B D(C + C) = A B D . |
| 34. | Find the output voltage for 011100 in a 6 bit R-2R ladder D/A converter has a reference voltage of 6.5 V. |
|||||||
Answer: Option B Explanation:
|
(an-1 2n-1 + an-2 2n-2 + .....a121 + a020)
(24 + 23 + 22) = 6.5 x 
= 2.84 .| 35. | Binary number 1101 is equal to octal number |
|||||||
Answer: Option C Explanation: 1101 = 13 in decimal = 15 (i.e., 8 + 5) in octal. |
