Homework Statement


Draw the logic circuit to represent the following Boolean expression only using NOR Gates:

Boolean expression F = overline(A + overline(B)) + overline(overline(A) + B), with overbars over the two bracketed sums and over the B and A terms.


Homework Equations

The Attempt at a Solution


Is this correct?
Logic circuit drawn only with NOR gates: inputs A and B feed NOR gates producing NOT A and NOT B, then further NOR stages with outputs labelled A-bar plus B, A plus B-bar, and the final output A plus B-bar plus A-bar plus B.

Thanks
 
Have you tried to test it using a boolean table of values?

Code:
A | B | output
------------------
0 | 0 |
0 | 1 |
1 | 0 |
1 | 1 |

Without testing it, it seems like its correct. I was able to follow your labeling and it made sense.
