State the principle of duality of Boolean algebraBoolean?

Principle of Duality helps us to find the possible correct boolean expression. "Any theorem or identity in switching algebra remains true if 0 and 1 are swapped and . and + are swapped." Mathematically f(x1,x2,...,xn,.,+,1,0)=f(x1,x2,...,xn,+,.,0,1) Important point to note is that dual of expression different from the complement of expression. Mathematically f(x1,x2,...,xn,.,+,1,0)=f(x1`,x2`,...,xn`,+,.,0,1); i.e. if x1 belongs to positive logic then x1` denotes the negative logic and vice versa. De-morgans law is helps us to obtain the complement of expression.
