DeMorgan's Theorem
The most important logic theorem for digital electronics, this theorem says that any logical binary expression remains unchanged if we
A practical operational way to look at DeMorgan's Theorem is that the inversion bar of an expression may be broken at any point and the operation at that point replaced by its opposite (i.e., AND replaced by OR or vice versa).
