You are given two circuit as shown in Fig.and . Which consists of NAND gates. Identify the logic operation carried out by the two circuits.
Text Solution
Verified by Experts
In Fig. the Boolean expression is, `y=bar(bar(A.B))=A.B`, i.e., AND gate is created. In Fig., the Boolean expression is, `y=bar(barA.barB)=bar(barA)+bar(barB)=A+B` i.e. OR gate is created.
