**Title: Drawing Logic Circuits for Boolean Expressions**

**Introduction:**

In digital electronics, understanding how to convert Boolean expressions into logic circuits is essential. Here, we will explore how to draw logic circuits for specific Boolean expressions.

**Boolean Expressions:**

1. **Expression 1:**  
   \( Y = (A + \overline{B})(C + D) \)

2. **Expression 2:**  
   \( Y = A + BC + D \)

**Instructions:**

For each expression, we'll break down the operations and guide you on how to construct the logic circuit:

- **Expression 1 Breakdown:**  
  - **Operation 1:** Calculate \( \overline{B} \) using a NOT gate.
  - **Operation 2:** Perform \( A + \overline{B} \) using an OR gate.
  - **Operation 3:** Perform \( C + D \) using another OR gate.
  - **Operation 4:** Combine the results of operations 2 and 3 using an AND gate to get the final output \( Y \).

- **Expression 2 Breakdown:**
  - **Operation 1:** Calculate \( BC \) using an AND gate.
  - **Operation 2:** Combine \( A \), the result of operation 1 \( BC \), and \( D \) using an OR gate to produce \( Y \).

**Conclusion:**

By following these steps, you can successfully draw the logic circuits for the given Boolean expressions. Practicing with various expressions will enhance your ability to design complex digital systems.
