Let's break down the given Boolean expression step by step:

The Boolean expression is: $F = (A \cdot \overline{B} + \overline{C}) \oplus (A \cdot \overline{B} \cdot C \cdot \overline{D}) \oplus (B \cdot \overline{D})$ Where:

• $A$, $B$, $C$, and $D$ are Boolean variables.
• $\overline{B}$, $\overline{C}$, and $\overline{D}$ represent the complements (negations) of $B$, $C$, and $D$.
• $\cdot$ represents AND, $+$ represents OR, and $\oplus$ represents XOR.

Step-by-Step Evaluation:

1. Expression 1: $A \cdot \overline{B} + \overline{C}$

   • This part performs an OR operation between $A \cdot \overline{B}$ and $\overline{C}$.

2. Expression 2: $A \cdot \overline{B} \cdot C \cdot \overline{D}$

   • This is a product (AND) of all the terms.

3. Expression 3: $B \cdot \overline{D}$

   • This is a product (AND) of $B$ and $\overline{D}$.

4. XOR between Expression 1 and Expression 2:

   • First XOR operation between $(A \cdot \overline{B} + \overline{C})$ and $(A \cdot \overline{B} \cdot C \cdot \overline{D})$.

5. XOR between the result of Step 4 and Expression 3:

   • Perform XOR between the result of the first XOR operation and $(B \cdot \overline{D})$.
