In the circuit, the logical value of A = 1 or B = 1 when potential at A or B is 5V and the logical value of A = 0 or B = 0 when potential at A or B is 0 V.
The truth table of the given circuit will be :
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
When both A and B 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
(AND gate)
