De Morgan's Theorem: NOR Form

EasyLogic CircuitAnalyze

CMOS logic families heavily favor NOR and NAND gates due to their efficient transistor-level implementation compared to standard OR and AND gates.

A logic block processes two input signals, A and B. The signals are routed through a single two-input NOR gate to produce intermediate signal W. The output is defined by the Boolean expression W = (A + B)'.

Determine the logical equivalent of this circuit using only AND and NOT operations. Evaluate the behavior of the transformation across all input combinations and apply the correct theorem to translate between the sum-based and product-based forms.

Constraints

  • Boolean expressions must use standard notation where ' denotes NOT, + denotes OR, and adjacent variables denote AND.
  • You must derive the equivalent expression algebraically without relying on a visual gate diagram.
