Minterm/Maxtern, SOP/POS

    1. The problem statement, all variables and given/known data

    Ok, so I have a digital electronics exam tomorrow, pretty confident with everything except when I should use minterms and maxterms.

    As I understand...

    using tabular method to find a minimum SOP expression I would use the minterms and if I need to find a minimum POS expression I would use the maxterms.

    2. Relevant equations
    For example:

    Use tabular method to find a minimum POS expression for the following, F(A,B,C,D)=M(0,2,3,8,12,13,15)

    I would simply use 0000,0010,0011.....etc

    However if I was asked to find the SOP I would have to convert to minterms so..
    F(A,B,C,D)=m(1,4,5,6,7,9,10,11,14)

    then I would use 0001,0100,0101....etc

    3. The attempt at a solution

    I am fine with the tabular method itself just confused with the above.

    Thankyou very much for anyone that can offer any insight.

    That is correct. Every function can be described as a sum of minterms, or a product of maxterms.
