- Any Boolean function that is expressed as a sum of minterms or as a product of max terms is said to be in its “canonical form”. It mainly involves in two Boolean terms, “minterms” and “maxterms”.

Example. Express the Boolean function F = x + y z as a sum of minterms. Solution: F = x + y z = x + (y z) AND (multiply) has a higher precedence than OR (add) = x(y+y')(z+z') + (x+x')yz expand 1st term by ANDing it with (y + y’)(z + z’), and 2nd term with (x + x’) = x y z + x y z' + x y' z + x y' z' + x y z + x' y z = m7 + m6 + m5 + m4 + m3

The sum of minterms form of a Boolean function is a representation where the function is expressed as the logical OR (sum) of its minterms. Each minterm corresponds to a unique combination of inputs that results in a TRUE output for the function.
Sep 30, 2024 · The minterms whose sum defines the Boolean function are those which give the 1’s of the function in a truth table. Since the function can be either 1 or 0 for each minterm, and since there are 2^n minterms, one can calculate all the functions that can be formed with n variables to be (2^(2^n)).
May 6, 2024 · Minterms and Maxterms are important parts of Boolean algebra. Minterm is the product of N distinct literals where each literal occurs exactly once. The output of the minterm functions is 1. Minterm is represented by m. Maxterm is the sum of N distinct literals where each literals occurs exactly once. The output of the maxterm functions is 0.
When a Boolean function or logical expression is expressed in the SSOP (Standard Sum of Product) Form or canonical form, then each term of the expression is called a minterm.
In Boolean algebra, any Boolean function can be expressed in the canonical disjunctive normal form (CDNF), [ 1 ]minterm canonical form, or Sum of Products (SoP or SOP) as a disjunction (OR) of minterms.
Converting a Boolean expression to a sum of minterms involves identifying the variables, creating a truth table, identifying minterms where the function is true, writing these in canonical form, and summing them.
