BOARD

Using a suitable combination from a NOR, an OR and a NOT gate, draw circuits to obtain the truth tables given below:

                                 3mark

Output not symmetric for A,B =(0,1) and (1,0). NOT gate in one input.                          1mark

(i) has three zero. NOR gate.                                                                                     1mark

Thus                                                              1mark
