Duality Theorem:
Duality theorem arises as a result of presence of two logic system i.e. positive & negative logic system.
This theorem helps to convert from one logic system to another.
From changing one logic system to another following steps are taken:
0 becomes 1, 1 becomes 0.
AND becomes OR, OR becomes AND.
‘+’ becomes ‘·’, ‘·’ becomes ‘+’.
Variables are not complemented in the process.
