**Question:**
For the Timing Waveform Diagrams shown below, which is the correct drawing for a NOR gate?

A. Drawing A  
B. Drawing B  
C. Drawing C  
D. Drawing D  

---

**Diagrams Explanation:**

Each diagram consists of three rows labeled A, B, and X, representing the input signals A and B, and the output signal X of a NOR gate.

**Drawing A:**
- Inputs A and B show varying high (1) and low (0) states.
- Output X is high only when both inputs A and B are low.

**Drawing B:**
- Inputs A and B show a similar pattern of alternating high and low states.
- Output X appears to be incorrect for a NOR gate as it does not stay low when any input is high.

**Drawing C:**
- Inputs A and B have synchronized patterns.
- Output X does not match the characteristic of a NOR gate.

**Drawing D:**
- Like the other drawings, inputs A and B fluctuate between high and low states.
- Output X rises when both inputs are low.

**Correct Answer:**
- The correct drawing for a NOR gate is **Drawing A**, where the output X is high only when both inputs A and B are low, which aligns with the NOR gate's truth table.
