The digital multiplexer is basically a combination logic circuit to perform the operation
| A. | AND-AND |
| B. | OR-OR |
| C. | AND-OR |
| D. | OR-AND |
|
Option: C Explanation : The equation for digital multiplexer includes AND and OR operations . For example AB+CD. So here firstly we have to solve AND operation then OR operation. Option is 'C'. Click on Discuss to view users comments. |

A toggle operation cannot be performed using a single
| A. | NOR gate |
| B. | AND gate |
| C. | NAND gate |
| D. | XOR gate |
|
Option: B Explanation :
For XOR gate complements the sinlge input eg if input 1 is given then you get 1 in output and vice versa This is called toggling.
Nand and NOR are universal gates and can be used to design XOR gate so they can also perform toggle operation.
Therefore correct answer is AND gate.
