Ex nor =((AB')+(A'B))'.
=(AB')'.(A'B)'
=(A'+B'').(A''+B')
=A'A+A'B'+BA+BB'
=A'B'+AB
Note; (a+b)'=a'.b'
a'a=0
b'b=0.
=(AB')'.(A'B)'
=(A'+B'').(A''+B')
=A'A+A'B'+BA+BB'
=A'B'+AB
Note; (a+b)'=a'.b'
a'a=0
b'b=0.

EX-NOR:AB+A'B'
A B Y
0 0 1
0 1 0
1 0 0
1 1 1
FROM above when INPUTS OF A and B or equal than only output Y=1(high).
