Math Problem Statement

You F =( A * (B(Compliment))) + C (Compliment)) XOR ((A*B(compliment)CD(compliment)) NOR (B * D(compliment))

Solution

To solve and simplify the given Boolean expression:

F=(AB+C)((ABCD)(BD))F = \left( A \cdot \overline{B} + \overline{C} \right) \oplus \left( (A \cdot \overline{B} \cdot C \cdot \overline{D}) \downarrow (B \cdot \overline{D}) \right)

where:

  • B\overline{B} denotes the complement (NOT) of BB,
  • \oplus denotes XOR (exclusive OR),
  • \cdot denotes AND (multiplication),
  • ++ denotes OR (addition),
  • \downarrow denotes NOR.

Step-by-Step Breakdown:

  1. Left Side: AB+CA \cdot \overline{B} + \overline{C} This part involves a simple OR operation between ABA \cdot \overline{B} and C\overline{C}.

  2. Right Side: (ABCD)(BD)(A \cdot \overline{B} \cdot C \cdot \overline{D}) \downarrow (B \cdot \overline{D}) This is the NOR operation between two terms:

    • The first term: ABCDA \cdot \overline{B} \cdot C \cdot \overline{D},
    • The second term: BDB \cdot \overline{D}.

    The NOR operation is equivalent to (ABCD)+(BD)\overline{(A \cdot \overline{B} \cdot C \cdot \overline{D}) + (B \cdot \overline{D})}.

  3. Apply XOR: The final step is to perform an XOR between the result of the left-hand side and the simplified result of the right-hand side.

Simplification Steps:

Let's proceed step-by-step to simplify each part:

  1. Simplify the left-hand side: AB+CA \cdot \overline{B} + \overline{C} This expression cannot be simplified further and remains as it is.

  2. Simplify the right-hand side: We need to simplify: (ABCD)(BD)=(ABCD)+(BD)(A \cdot \overline{B} \cdot C \cdot \overline{D}) \downarrow (B \cdot \overline{D}) = \overline{(A \cdot \overline{B} \cdot C \cdot \overline{D}) + (B \cdot \overline{D})} First, simplify the OR: (ABCD)+(BD)(A \cdot \overline{B} \cdot C \cdot \overline{D}) + (B \cdot \overline{D}) This expression involves two terms, but they cannot be simplified further because they don't share common factors. Thus, the NOR is: (ABCD)+(BD)\overline{(A \cdot \overline{B} \cdot C \cdot \overline{D}) + (B \cdot \overline{D})}

  3. Final Expression: The Boolean function FF is: F=(AB+C)(ABCD)+(BD)F = \left( A \cdot \overline{B} + \overline{C} \right) \oplus \overline{(A \cdot \overline{B} \cdot C \cdot \overline{D}) + (B \cdot \overline{D})}

This expression involves an XOR operation, so the simplification of the expression would require testing its behavior in truth tables to see if further reduction is possible.

Would you like me to expand this with a truth table to check equivalence?
