Question

In the circuit, the logical value of ( $A=1$ or $B=1$ ) when potential at $A$ or $B$ is 5 V 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

Professor PC Thomas Classes · Answer

(a) : When both $A$ \& $B$ have logical volume ' $I$ ' both diode are reverse bias and correct well flow in resistor hence output will be 5 volt logical volume ' T ' In all after cases conduction will take place hence output will be zero volt so. It is AND gate. So, the truth table is
