Demorgans theorem demorgans theorem is mainly used to solve the various boolean algebra expressions. Arnold schwarzenegger this speech broke the internet and most inspiring speech it changed my life. For two variables a and b these theorems are written in boolean notation as follows. In each case, the resultant set is the set of all points in any shade of blue. B thus, is equivalent to verify it using truth tables. This law allows expressing conjunction and disjunction purely in terms of each other through negation. Demorgans theorem and laws basic electronics tutorials. Solving these types of algebra with demorgans theorem has a major application in the field of digital electronics. It is used for implementing the basic gate operation likes nand gate and nor gate.

The compliment of the product of two variables is equal to the sum of the compliment of each variable. Similarly, is equivalent to these can be generalized to more than. The easiest way to remember demorgans law is that you flip the symbol upside down which changes union to intersection and vice versa, complement both sets remembering that the complement of a complement is just that set, and either remove parentheses or add parentheses and place the complement symbol outside of it. It is also used in physics for the simplification of boolean expressions and digital circuits. The left hand side lhs of this theorem represents a nand gate with inputs a and b, whereas the right hand side rhs.
