     A logic gate has the inputs A and B shown below. Note that each input varies with time. The corresponding output C is also shown. Identify the gate.  NOT  AND  NOR  OR  NAND    
 
  
  Solution
the turth table of the timing diagram will be :
it is simillar to NAND gate turth table :
so the answeer is NAND gate
| A | B | C | 
| 1 | 1 | 0 | 
| 1 | 0 | 1 | 
| 0 | 0 | 1 | 
| 0 | 1 | 1 |
