Teaching DSSSB TGT Mock Test 2025 Digital Logic Number Representations and Computer Arithmetic Minimization of Boolean Expression
The De Morgan's theorem states that the NOT of a conjunction is equal to the disjunction of the NOTs, and the NOT of a disjunction is the conjunction of the NOTs. Which of the following expressions appropriately represents this theorem?
1
(A + B)' = A' * B', (A * B)' = A' + B'
2
(A + B)' = A' + B', (A * B)' = A' * B'
3
(A + B)' = A' * B', (A * B)' = A' * B
4
(A + B)' = A' + B', (A * B)' = A' + B
