Difference Between SOP and POS

ComputersComputer ProgrammingServer Side Programming

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.
