You are given the two circuits as shown in Fig. and . Show that circuit acts as OR gate while the circuit acts as AND gate.
Text Solution
Verified by Experts
In Fig. , the first gate is a NOR gate and second gate is NOT gate. The Boolean expression of this combination of gates is `y'=bar(A+B)=barA.barB` `y=bar(y^('))=bar(baAr.barB)=bar(barA)+bar(barB) =A+B` i.e., `y=A+B`. It is a Boolean Expression of OR gate. Thus, circuit acts as OR gate. In Fig. the output of two NOT gates is made input to a NOr gate. The Boolean expression of teh combination of gates is `y = bar(barA+ barB) =barbarA.barbarB =A.B` i.e., `y = A.B.` It is a Boolean Expression of AND gate. Thus, circuit acts as AND gate.
