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 Modulation Types:**
- FM stands for Frequency Modulation, while AM stands for Amplitude Modulation. Both are techniques used to encode information onto a carrier wave for transmission.

2. **Noise Levels:**
- FM broadcasts are less susceptible to noise compared to AM broadcasts. Noise can interfere with the quality of the signal, and since FM uses frequency changes to convey information, it is better at rejecting noise.

3. **Quality of Reproduction:**
- The reproduction quality of FM signals is generally superior to that of AM signals. This is because FM can carry more information and has a wider bandwidth, allowing for clearer sound reproduction.

4. **Conclusion:**
- Therefore, FM broadcast is preferred over AM broadcast due to two main reasons: it is less noisy and provides better quality reproduction of sound.

5. **Final Answer:**
- FM broadcast is preferred over AM broadcast because it is less noisy and has better quality reproduction.
