| Q. |
How many OR gates are required for an octal-to- binary encoder? |
| A. | 3 |
| B. | 2 |
| C. | 8 |
| D. | 10 |
| Answer» A. 3 | |
| Explanation: an encoder is a combinational circuit encoding the information of 2n input lines to n output lines, thus producing the binary equivalent of the input. thus, in octal to binary encoder there are 8 (=23) inputs, thus 3 output lines. | |
