Truth Table to Canonical SOP

EasyLogic CircuitAnalyze

Digital synthesis tools convert behavioral descriptions into Boolean equations to map logic onto physical gates. The truth table below defines a 3-variable logic function with inputs A, B, and C, and output F.

| A | B | C | F | |---|---|---|---| | 0 | 0 | 0 | 1 | | 0 | 0 | 1 | 0 | | 0 | 1 | 0 | 1 | | 0 | 1 | 1 | 0 | | 1 | 0 | 0 | 0 | | 1 | 0 | 1 | 1 | | 1 | 1 | 0 | 1 | | 1 | 1 | 1 | 1 |

Identify the active minterms and derive the canonical sum-of-products expression for F.

Constraints

  • The variables must be evaluated in the order A (MSB), B, C (LSB).
  • A minterm includes all input variables exactly once.
  • A canonical Sum of Products (SOP) expression contains no simplified terms.
