What is the output of the circuit for the input values given? (SEE IMAGE)

 

**Title: Circuit Analysis for Given Input Values**

**Question:**

9. What is the output of the circuit for the input values given?

**Input Signals:**

- \( P = 0 \)
- \( Q = 0 \)
- \( R = 0 \)

**Circuit Description:**

The circuit consists of three main logic gates: two OR gates, one AND gate, and one NOT gate.

1. **First OR Gate:**
   - Inputs: \( P \) and \( Q \)
   - The output will be high (1) if either \( P \) or \( Q \) is high.

2. **AND Gate:**
   - Inputs: \( Q \) and \( R \)
   - The output will be high (1) only if both \( Q \) and \( R \) are high.

3. **NOT Gate:**
   - Input: Output of the AND gate
   - Inverts the input signal. If the output of the AND gate is 0, the NOT gate will output 1, and vice versa.

4. **Second OR Gate:**
   - Inputs: Output of the first OR gate and output of the NOT gate
   - The output will be high (1) if either input is high.

**Analysis:**

- For the given input signals \( P = 0 \), \( Q = 0 \), \( R = 0 \):
  - The first OR gate receives inputs 0 and 0, so its output is 0.
  - The AND gate receives inputs 0 and 0, so its output is 0.
  - The NOT gate inverts the AND gate's output, changing 0 to 1.
  - The second OR gate receives inputs 0 (from the first OR gate) and 1 (from the NOT gate), resulting in an output of 1.

**Output:**

The output \( S \) for the input values given is 1.
