Boolean logic is a form of algebra that deals with binary variables and binary logic functions. It is widely used in electronic circuits, computer programming, and digital signal processing. One of the fundamental concepts in boolean logic is deMorgan's theorem.

deMorgan's Theorem

deMorgan's theorem is a set of rules that deal with the negation of logical operators. It states that the negation of a logical operator applied to a set of variables is equivalent to the opposite operation applied to the negation of those variables.

In other words, if we have a set of variables {A, B, C, ...} and a logical operator such as AND or OR, then the negation of the operator applied to these variables is equivalent to the opposite operation applied to the negation of the variables.

For example, let's consider the following expression:

NOT (A AND B)

Using deMorgan's theorem, we can rewrite this expression as follows:

(NOT A) OR (NOT B)

Similarly, if we have the expression:

NOT (A OR B)

Using deMorgan's theorem, we can rewrite this expression as follows:

(NOT A) AND (NOT B)

deMorgan's theorem is a powerful tool in boolean logic. It allows us to simplify complex expressions and make them more readable. By applying this theorem, we can easily convert between different logical operators and their negations, which makes it easier to design and analyze digital circuits and computer programs.
