Minterm Expansion Walkthrough

← Back to Unit 4

Description

This interactive walkthrough demonstrates how to expand a Boolean expression into its canonical Sum-of-Minterms form. Starting with F(A,B,C) = A'B + BC', each term is expanded to include all variables by multiplying by the appropriate (X + X') = 1 identity.

Learning Objectives

Bloom Level: Apply (L3)

After using this MicroSim, students will be able to:

  • ✓ Apply the minterm expansion technique to convert expressions to canonical form
  • ✓ Identify missing variables in product terms
  • ✓ Use the identity (X + X') = 1 to expand terms
  • ✓ Convert between algebraic and minterm list notation

How to Use

  1. Click Next → to advance through each expansion step
  2. Watch as each term is identified and expanded
  3. See how missing variables are added using (X + X') = 1
  4. Observe duplicate minterms being removed
  5. Click ← Previous to review earlier steps
