Difference Between SOP and POS
In this post, we will understand the difference between SOP and POS −
SOP (Sum of Product)
It helps represent boolean expressions as sum of product terms.
It uses minterms.
Minterm can be understood as a product of boolean variables (in normal form or complemented form).
It is calculated as the sum of minterms.
Minterms can be represented using the letter ‘m’
It is formed by taking into consideration all of minterms, whose output is HIGH(1).
When minterms are written for SOP, input that has value 1 is considered as the variable.
When minterms are written for SOP, input that has value 0 is considered as complement of
the input.
POS (Product of Sum)
It helps represent boolean expressions as product of sum terms.
It uses maxterms.
Maxterm can be understood as the sum of boolean variables (in normal form or complemented form).
It is calculated as the product of maxterms.
Maxterms can be represented using the letter ‘M’
It is formed by taking into consideration all of the maxterms, whose output is LOW(0).
When maxterms are written POS, input that has value 1 is considered as the complement.
When maxterms are written for POS, input that has value 0 is considered as the variable
itself.
