De Morgan's Applied to a Multi-Variable Expression

MediumLogic CircuitAnalyze

Hardware synthesis tools rely on De Morgan's laws to map complex logic equations into available standard cell libraries. Pushing negations through a logic network changes AND gates to OR gates and vice versa.

The boolean expression provided is F = (ABC + D)'. This represents a multi-level logic path where a wide AND gate feeds into a NOR structure.

Apply De Morgan's theorem to distribute the outer complement down to the individual variables. Identify the correct intermediate steps and determine the final simplified expression.

Constraints

  • Standard Boolean algebra rules and operator precedence apply: NOT, AND, OR.
  • Variables grouped by parentheses or implicit multiplication must be treated as a single term during outer complement expansion.
