FM boradcast is preferred over AM broadcast because

Options

A. it is less noisy.
B. reproduction is of much better quality.
C. it is more noisy.
D. both a and b

Explanation

### Step-by-Step Solution:

1. **Understanding FM and AM:**
- FM stands for Frequency Modulation, while AM stands for Amplitude Modulation.
- In FM, the frequency of the carrier signal varies according to the amplitude of the incoming message signal.
- In AM, the amplitude of the carrier signal varies according to the amplitude of the incoming message signal.

2. **Noise Levels:**
- FM broadcasting is less susceptible to noise and interference compared to AM broadcasting.
- Noise can significantly affect the quality of AM signals, making them more prone to distortion and static.

3. **Bandwidth:**
- FM has a wider bandwidth than AM.
- The wider bandwidth in FM allows for better sound quality and fidelity, making it more suitable for music and high-fidelity audio.

4. **Reproduction Quality:**
- The reproduction quality of FM signals is generally better than that of AM signals.
- This means that FM can reproduce sound more accurately, which is particularly important for music and other audio content.

5. **Conclusion:**
- Due to its lower susceptibility to noise, wider bandwidth, and better reproduction quality, FM broadcasting is preferred over AM broadcasting.
