Question

Which of the following frequencies does not belong to FM broadcast?

• A. $64 \,MHz$
• B. $106 \,MHz$
• C. $99\, MHz$
• D. $89 \,MHz$

Answer 1

The Correct Option is A

To identify which frequency does not belong to FM broadcast, it's important to understand the typical frequency range allocated for FM radio broadcasting.

FM Broadcast Frequency Range:
The internationally allocated frequency band for FM radio broadcasting is from \(88 \, \text{MHz}\) to \(108 \, \text{MHz}\). This range is specifically used for transmitting frequency modulation audio programming.

Analyzing the Options:

1. \(64 \, \text{MHz}\): This frequency is below the FM broadcast range. It typically falls into VHF (Very High Frequency) but is not used for commercial FM broadcasting.
2. \(106 \, \text{MHz}\): This frequency falls within the FM broadcast range.
3. \(99 \, \text{MHz}\): This frequency is also within the FM broadcast range.
4. \(89 \, \text{MHz}\): This frequency is within the FM broadcast range as well.

Therefore, the frequency \(64 \, \text{MHz}\) does not belong to the FM broadcast frequency range, making it the correct answer.
