The operation of a staircase switch best explains the
| A. | or operation |
| B. | and operation |
| C. | exclusive nor operation |
| D. | exclusive or operation |
Answer : D Explanation : First from the truth table of the exclusive OR operation.If both the switches are off i-e 0, 0 then the light will be off i-e, 0. So, 0, 0 yields 0.If you switch on either of the two switches i-e. 0 1 or 1 0, the light will be on. So, 0 1 yields 1 (so does 1 0 ).Now, if you switch on the other one, which is currently off, it will be 1 1. This should yield a 0. Compare these results with the truth table of XOR. |
