| 11. | If an analog voltage is expressed in binary using 4 bits, each successive binary count would represent |
|||||||
Answer: Option C Explanation: Since 1111= decimal 15, each successive binary count represent 1/15 of total voltage. |
of total voltage
of total voltage
of total voltage
of total voltage| 12. | In a 4 input AND gate, the total number of High outputs for 16 input states are |
|||||||
Answer: Option D Explanation: In only one combination are all inputs high. |
| 13. | Symmetrical square wave of time period 100 μs can be obtained from square wave of time period 10 μs by using |
|||||||
Answer: Option C Explanation: Frequency has to be divided by 10. |
| 14. | The Boolean expression for the shaded area in the Venn diagram is |
|||||||
|
| 15. | The initial state of a Mod-16 counter is 0110. After 37 clock pulses the state of counter will be |
|||||||
Answer: Option A Explanation: After 37 clock pulses the state will be the same as after (37 - 32), i.e., 5 clock pulses. 6 + 5 = 11. Hence 1011. |
