Algebraic Forms of Switching Functions (2)

• A minterm is a product term in which all the variables appear exactly once either complemented or uncomplemented.

• Canonical Sum of Products (canonical SOP):

  • Represented as a sum of minterms only.
  • Example: f1(A,B,C) = A'BC' + ABC' + A'BC + ABC (2.1)

• Minterms of three variables:
