In the circuit, the logical value of
or
when potential at
or
is
and the logical value of
or
when potential at
or
is
.

The truth table of the given circuit will be:
Text Solution
Verified by ExpertsA
When both
and
have logical value ' 1 ' both diode are reverse bias and current will flow in resistor hence output will be 5 volt i.e. logical value ' 1 '. In all other case conduction will take place, hence output will be zero volt i.e. logical value ' 0 '.
So, truth table is
A
B
Y
