The Boolean expression you provided is: $A \lnot B + A \lnot C + B \lnot C$. To convert this into a logic circuit, we can follow these steps:

1. Break down the expression into individual terms:

• The first term is $A \lnot B$, which is the AND operation between $A$ and the NOT of $B$.
• The second term is $A \lnot C$, which is the AND operation between $A$ and the NOT of $C$.
• The third term is $B \lnot C$, which is the AND operation between $B$ and the NOT of $C$.

2. Combine using OR gates:

• The final expression $A \lnot B + A \lnot C + B \lnot C$ is an OR operation between the three terms.

Components Needed:

• AND gates: One for each term (three in total).
• NOT gates: To negate $B$ and $C$.
• OR gate: To combine the results of the AND gates.

Steps for Drawing the Circuit:

1. NOT gates:

   • Input $B$ into a NOT gate to produce $\lnot B$.
   • Input $C$ into a NOT gate to produce $\lnot C$.

2. AND gates:

   • First AND gate: Takes $A$ and $\lnot B$ as inputs.
   • Second AND gate: Takes $A$ and $\lnot C$ as inputs.
   • Third AND gate: Takes $B$ and $\lnot C$ as inputs.

3. OR gate:

   • Combine the outputs of the three AND gates using an OR gate.

Now, I'll summarize this into a circuit diagram description:

1. NOT gates: $B$ goes to a NOT gate for $\lnot B$, and $C$ goes to a NOT gate for $\lnot C$.
2. AND gates:
   • The first AND gate has inputs $A$ and $\lnot B$.
   • The second AND gate has inputs $A$ and $\lnot C$.
   • The third AND gate has inputs $B$ and $\lnot C$.
3. OR gate: The three AND gate outputs are connected to an OR gate.
